Dereck Lively II Expected To Be Ready For Camp

August 17th, 2025 at 7:02pm CST by Eli Cohen

Dereck Lively II is expected to be ready for the Mavericks‘ training camp following offseason foot surgery, writes Grant Afseth for Dallas Hoops Journal.

Lively underwent a procedure to clean up bone spurs in his right foot in July and was initially in a walking boot. This followed a diagnosis of a stress fracture in the same foot in January. Previous reports indicate that the handling of Lively’s foot injury had led to a confrontation between the team’s director of health and performance, Johann Bilsborough, and the athletic performance director, Keith Belton (Belton has since been let go).

Lively’s foot issue limited him to 36 games last season, during which time he averaged 8.7 points, 7.5 rebounds, 2.4 assists, and 1.6 blocks in 23.1 minutes per night.

On Saturday, the Mavs posted a video of Lively working out in Philadelphia, where he has been training with head video coordinator Riley Crean (Twitter video link).

In addition to his rehabilitation, Lively has spent a large part of the offseason in communication with new Maverick Cooper Flagg, giving him advice and helping him get acclimated to the NBA world.

Southwest Notes: Lively, Flagg, Giannis, Wembanyama, Sengun, Durant, Smith Jr.

Mavericks center Dereck Lively II has only two years of NBA experience but he’s playing a mentorship role to top pick Cooper Flagg, according to Jake Rogers of Dallas Hoops Journal. Naturally, they have a college connection, as both were one-and-dones at Duke.

“I’ve probably known him for a couple of years now, at least two or three,” Lively said. “He’s always been the same smiling, joking kid. I’m glad he’s been able to stay grounded, not letting the spotlight overwhelm him. Whether he’s in the gym or hanging out at the house, he’s always just being Coop.”

Lively has stayed in frequent contact with Flagg since the draft.

“I’m making sure he feels as comfortable as possible, giving him any little detail or advice. I remember how frightened I was at 19. He’s only 18,” Lively said.

Here’s more from the Southwest Division:

Bucks forward Giannis Antetokounmpo has carved out a Hall of Fame worthy career but he’s also into collecting memorabilia of other NBA superstars. His current target is Spurs big man Victor Wembanyama, he told Brooks Peck of The Athletic during an appearance at the National Sports Collector Convention. “I want Wemby’s first rookie card ever,” Antetokounmpo said. “I think he’s gonna be one of the best players in the league in the next couple of years. I think he will have a very great career moving forward, so — maybe like a jersey, his first jersey or his first basketball shoe when he played his first NBA game, or the first ball that he played with and scored his very first point. You gotta go with Wemby, Steph (Curry), LeBron (James), MJ (Michael Jordan). Those are great investments.”
Rockets center Alperen Sengun believes the offense will thrive with the addition of Kevin Durant. Sengun, who will play for Turkey in EuroBasket, made his comments to Anadolu, Turkey’s state-run news agency (hat tip to RocketsWire). “I’m excited to play with Durant. Everyone is excited to play with him. It doesn’t matter his age — ultimately, he’s Kevin Durant. I have no doubt he will bring a lot to the team,” Sengun said. “He’s very experienced, and we have some very young players. I think he’ll open up the game for us. He’s incredibly effective both offensively and defensively.”
Along the same lines, Rockets forward Jabari Smith Jr. said he believes playing with Durant will be a learning experience, RocketsWire relays via an interview with Space City Home Network’s Vanessa Richardson. “Kevin Durant is one of the greatest players to ever touch a basketball,” Smith said. “It’s going to be great for me to learn from him, and see what he does, day-to-day… and just soak up as much game as I can. It’s going to be fun playing alongside him and going to battle with him.”

Mavs Notes: Davis, Lineups, Arena Site, Casson, Preseason

July 29th, 2025 at 7:47pm CST by Dana Gauruder

Injuries prevented the Mavericks from taking a long look at double-big lineups last season. They plan to utilize their size next season in the hopes of making a deep playoff run, Christian Clark of The Athletic writes.

Clark notes that Anthony Davis logged only 95 minutes with either Dereck Lively II or Daniel Gafford in the middle. Davis is expected to play the bulk of his minutes at power forward next season.

“That’s something we have a huge advantage (with) going forward: our size,” Mavericks assistant coach Josh Broghame said. “The talent with that size, that’s something we put on a premium here, and it’s been really, really good for us so far.”

Here’s more on the Mavs:

In the same story, Clark projects the opening night lineup, with Davis and Lively joined by top pick Cooper Flagg in the frontcourt and D’Angelo Russell and Klay Thompson starting in the backcourt. P.J. Washington, Gafford, Caleb Martin, Naji Marshall and Dante Exum or Max Christie are projected to fill out the rotation.
Mavericks CEO Rick Welts said that multiple sites for a new arena are being considered and the process is in the early stages. “We have been presented several sites by the city and we are doing a deeper dive on two of them currently to see how viable they are,” he told Brad Townsend of the Dallas Morning News. “Neither may work and we may refocus on others.” Welts has set a goal of choosing a site by the end of the year or early next year. “The process is going to go on, I would guess, for months. But, no, we’re not like on the 10-yard line,” he added.
Ethan Casson has been named president of business operations for the franchise, Townsend reports in a separate story. Casson announced last month he would step down after nine years as the Timberwolves’ CEO after the sale of the franchise was finalized. He will report to Welts once his new job officially begins on Aug. 11.
The Mavs will play an Oct. 6 preseason game against the Thunder in Fort Worth, according to Grant Afseth of the Dallas Hoops Journal, as well as a neutral site preseason contest in Las Vegas against the Lakers on Oct. 15. The remainder of the preseason slate has yet to be revealed.

Mavs’ Dereck Lively Undergoes Right Foot Procedure

July 15th, 2025 at 1:08pm CST by Luke Adams

Mavericks center Dereck Lively recently underwent surgery to clean up bone spurs in his right foot, according to reports from Marc Stein of The Stein Line and Shams Charania of ESPN (Twitter links).

Lively was in a walking boot following the procedure, but has since gotten out of that boot, tweets Stein. According to Charania, the expectation is that the big man will be healthy for training camp this fall.

The right foot is the same one that Lively injured earlier this year. He was diagnosed in January with a small fracture in his foot/ankle area, which sidelined him until April and limited him to 36 total games in 2024/25. He averaged 8.7 points, 7.5 rebounds, 2.4 assists, and 1.6 blocks in 23.1 minutes per night in those 36 appearances.

Reporting in the spring indicated that a disagreement over how to treat Lively’s foot injury resulted in a “loud, heated confrontation” between Mavericks director of player health and performance Johann Bilsborough and athletic performance director Keith Belton, which led to an HR investigation. Belton has since been let go by the team.

As Stein points out, Lively’s surgery means that three important Mavericks players are now recovering from surgeries. Kyrie Irving, of course, is making his way back from an ACL tear, while Anthony Davis recently underwent a procedure to repair a detached retina.

Mavs Notes: Frontcourt, Washington, Flagg, Free Agency, Sweeney, Lottery Luck

June 26th, 2025 at 6:27pm CST by Dana Gauruder

The Mavericks frontcourt might seem a little crowded with Dereck Lively, Anthony Davis, P.J. Washington and Daniel Gafford — who just agreed to an extension — joined by top pick Cooper Flagg.

However, general manager Nico Harrison indicated he’s planning to have all of them sharing minutes, rather than moving one of the veterans. He also envisions Washington, the incumbent starting small forward, playing together with Flagg at times. Harrison even brought up the subject with Washington.

“I said, ‘Hey, P.J., you think you guys can play together?’ ” Harrison recalled, per Brad Townsend of the Dallas Morning News. “He’s like, ‘Oh yeah, we can play together.’ So I don’t see any jealousy. I think guys are excited to play with him and as he’s ready, he’s gonna get more and more opportunities.”

By winning the draft lottery, Harrison believes the team will be contenders for years to come.

“I think it’s win now. It’s also win in the future,” Harrison said. “Eventually it’s going to be Cooper’s team. We don’t know when that transition will happen. So I think it’s win now and then set yourself up to win in the future as well.”

Here’s more on the Mavs:

Harrison envisions Flagg as making an impact in a variety of ways, Grant Afseth of the Dallas Hoops Journal relays. “He’s a basketball player. He can handle the ball, he can shoot, he can make plays for people. He’s a good passer,” Harrison said. “He’s going to be on the floor. The big thing is: who can he defend? And he’s a great defender.”
Harrison said the Mavs will look in free agency to fill the temporary void left by Kyrie Irving‘s ACL injury but it won’t necessarily be a traditional point guard. “I’m not really worried about someone to run the offense. I think we’ve got enough guys that can handle the ball and play multiple positions — just someone to get us organized,” Harrison said, per Afseth, adding, “A lot of players want to come play in Dallas.”
Harrison became extremely unpopular with fans after trading Luka Doncic but the franchise’s lottery luck seems to have to toned down the vitriol, he notes. “I’ve seen the fans react since we got the No. 1 pick. It feels like they’re feeling really good and optimistic about the future,” he said, according to Afseth. “I’m hoping so. I’m assuming so — a little bit maybe.”
Harrison emphasized during his press conference that Jason Kidd was staying put as head coach, dousing speculation that Kidd could wind up with the Knicks. Sean Sweeney‘s agent, Andy Miller, told Townsend (Twitter link) that Dallas did want to keep Sweeney but that the Spurs offered the highly regarded assistant a “bigger role.” “Sean’s contract was expiring,” Miller said. “Dallas made a yeoman’s effort to obviously retain him. They wanted to keep him. I think for Sean this is an opportunity to have a bigger role, a bigger say, more input, with an upward trajectory…”
A team source told ESPN’s Baxter Holmes that the organization was stunned when it drew the top combination in the lottery last month. “We never even considered that the impossible could happen on May 12,” the source said. “I’m not sure there has ever been a more abrupt reversal of fortune.”

Mavs Rumors: Health/Performance Team, Doncic, Dumont, Harrison, Kidd

April 22nd, 2025 at 4:01pm CST by Luke Adams

Within an in-depth story focused on the changes made with the Mavericks‘ health and performance department in recent years, Tim MacMahon of ESPN shares several details that reflect poorly on the team’s current management, starting with the firing of longtime director of health and performance Casey Smith in 2023.

As MacMahon explains, several sources believe general manager Nico Harrison fired Smith – who was close with longtime Mavs star Dirk Nowitzki as well as Luka Doncic – because he wasn’t enough of a yes-man.

“(Harrison) was 100 percent threatened by him,” a team source told MacMahon. “He’s going to show that I’m in charge and nobody else can question that.”

MacMahon also reports that the relationship between new director of player health and performance Johann Bilsborough and athletic performance director Keith Belton has been frosty, writing that Bilsborough doesn’t respect Belton’s acumen. Belton was hired by the Mavs first, with Bilsborough later hired as his superior.

A January disagreement over how Dereck Lively‘s foot injury was being handled led to a “loud, heated confrontation” between the two men, according to MacMahon, who hears from one source that the altercation was “coming for a long time.”

Here’s more on the Mavs:

Both MacMahon and Grant Afseth of Dallas Hoops Journal (Substack link) say the calf strain Doncic sustained on Christmas Day was a source of major tension between the Mavs and the guard’s camp. The team believed that Doncic could be back in two to three weeks and Harrison thought the injury was related to Doncic’s conditioning, whereas the star guard’s camp was adamant that he needed to sit out for six weeks to fully recover and believed the injury stemmed from the fact that he returned too soon from a previous heel issue. “That deepened the divide,” a source told ESPN.
In the wake of the Doncic trade, Mavericks governor Patrick Dumont no longer views Harrison as having “irreproachable basketball expertise,” sources tell Tim Cato of DLLS Sports (subscription required). Dumont has been especially frustrated that Harrison either didn’t foresee or didn’t better prepare him for the extreme negative reaction to the trade from the fan base, Cato adds.
Within the same story, Cato cites sources who say that Jason Kidd “resented” the Doncic trade, even though the Mavs head coach shared some of Harrison’s frustrations about Doncic’s work habits. Kidd felt he was being asked to reinvent a roster and a system that had previously been built around Doncic, Cato explains, noting that the coach’s frustration was a factor in his decision to skip a mandatory press conference in February on the same day Doncic made his Lakers debut.

Mavs GM Harrison On Doncic Trade, Fan Reaction, More

April 21st, 2025 at 4:14pm CST by Rory Maher

At a press conference on Monday afternoon, Mavericks general manager Nico Harrison discussed the shocking decision to trade Luka Doncic as well as the overwhelmingly negative reaction to it from fans, who have been chanting “fire Nico” since the deal was completed.

“I did know Luka was important to the Mavs’ fan base,” Harrison said, per RealGM. “I didn’t quite know to what level.

“But, really, the way we looked at it is if you’re putting a team on the floor that’s Kyrie [Irving], Klay [Thompson], P.J. [Washington], Anthony Davis and [Dereck] Lively, we felt that’s a championship-caliber team. And we would have been winning at a high level. That would have quieted some of the outrage. So unfortunately we weren’t able to do that, so it just went on and on.”

When asked why he should be able to keep his job, Harrison defended his Mavericks tenure, tweets Mike Curtis of The Dallas Morning News.

“Well, one, I think I’ve done a really good job here,” Harrison said. “And I don’t think I can be judged by the injuries this year. You have to judge the totality, from the beginning to end. I think I have a really good working relationship with [governor Patrick Dumont]. I think you add in Rick [Welts], the leadership we have is really elite and you’ll see next year when our team comes back. We’re going to be competing for a championship.”

Here’s more from Harrison’s press conference:

Harrison was pressed on why the Mavericks couldn’t get more assets from the Lakers for Doncic. “I think the biggest thing is if you don’t value AD as an All-NBA player and All-Defensive player, then you’re not going to like the trade,” Harrison said, according to Curtis (Twitter link).
The Mavs’ head of basketball operations said Dumont didn’t pressure him to make the deal, as Curtis relays (via Twitter). “Not at all. Patrick reminds me of the leadership that I had at Nike and a really good leader doesn’t tell the people that work for him what to do. It’s a collective, well thought out process to make a big move like that. Also, unfortunately, I’m super stubborn so someone telling me to do something doesn’t work too well for me.”
Despite the intense backlash, Harrison claims his relationship with Dumont has actually been “strengthened” in the two-plus months since the trade was made, according to Marc Stein (Twitter link).
Harrison said Davis won’t need surgery this offseason and he doesn’t believe Lively will either, per Brad Townsend of The Dallas Morning News (Twitter link). Both players missed significant time with injuries, but were able to return before the team was eliminated in the play-in tournament.
Regarding Kyrie Irving‘s $43.96MM player option for 2025/26, Harrison said he wasn’t sure if it would be exercised, but he’s confident the 33-year-old will be in a Mavericks uniform next season. “It’s too early to tell what Kyrie is going to do, but what I do feel is he’s going to be a Maverick next year,” Harrison said (Twitter link via Curtis).

Mavs Notes: Thompson, Davis, Lively, Offseason

April 19th, 2025 at 12:42pm CST by Luke Adams

After the Mavericks‘ season came to an end as a result of Friday night’s play-in loss in Memphis, Klay Thompson described his first year in Dallas as “tumultuous.” Head coach Jason Kidd took a rosier view, as Tim MacMahon of ESPN.com relays, referring to 2024/25 as an “incredible season” for his team, which missed out on the playoffs after making the NBA Finals last spring.

“When you look at the injuries that we’ve had (and) the change, for us to even be here playing in (Friday’s play-in) game, it’s incredible,” Kidd said. “It just shows the character of that group in that locker room, the fight, being prepared, moving on, learning from our losses and also our wins. So an incredible season with the change and injuries. Some would say we shouldn’t even be here, so give those guys in that locker room a lot of credit.”

While Kidd was eager to praise his players for the way they fought through the season, the fact that so much fight was required at all is a reflection of why Thompson viewed it as “tumultuous.” The second half was defined by a series of injuries to key players and the fallout of the controversial Luka Doncic trade.

When Thompson signed with the Mavericks as a free agent last summer, he was hoping to be the missing piece for a club that was three wins away from a championship in 2024. Instead, he’ll be watching his former team (Golden State) from home during the first round of the playoffs after averaging just 14.0 points per game in his first season as a Maverick, his lowest scoring mark since his rookie year.

“Don’t do this to me. Don’t do that to me. Don’t do that,” Thompson said with a laugh when asked if he’d still join the Mavs if he could do his 2024 free agency over. “That’s kind of a ridiculous question. I don’t own a time machine, and I don’t believe in going back, looking back. If I did that my whole career, I would not be where I’m at and I wouldn’t have been able to persevere through two really hard injuries.

“So I’m here in Dallas, and I enjoyed my time and I’m looking forward to the future.”

Here’s more on the Mavs as their offseason gets underway:

Anthony Davis, who scored 40 points in Friday’s loss, said after the game that he appreciated the way that Mavericks fans treated him after his midseason arrival, even though he knows many of those fans disliked the trade the team made to acquire him. “Obviously, it’s a lot of emotions. I know it’s not directed towards me,” Davis said, per Mike Curtis of The Dallas Morning News. “The city loved the guy (Doncic). Get rid of a guy. A new guy comes in, yet they want to embrace you and they’re thankful for you, it still stings. I’m just thankful and appreciative of the city of Dallas and the fans for welcoming me and Max (Christie) to the new situation.”
Mavericks center Dereck Lively was on a minutes restriction for both of the team’s play-in games this week, tweets NBA insider Marc Stein. Lively, who was out from mid-January to early April with a foot injury, played 18 minutes on Wednesday vs. Sacramento and 20 minutes on Friday vs. Memphis.
According to Stein (Twitter link), Lively’s foot injury was “at the center of some significant tensions” among some of the new members of the Mavs’ medical and performance team at the practice facility in February. President of basketball operations Nico Harrison defended the medical team during this week’s media session when asked how Lively was on the verge of returning to action in January before being diagnosed with a stress fracture. “It actually goes to show the strength of our medical team, because he was cleared to play, but his signs and symptoms—our medical team knew it was something more,” Harrison said. “And so that’s why they went and tested him again and saw the CT scan. They actually avoided a potential catastrophic injury.”
Bobby Marks of ESPN has shared his preview of the Mavericks’ offseason in a YouTube video and in an ESPN.com Insider-only article. Marks explores what a new contract for injured guard Kyrie Irving might look like and identifies forward P.J. Washington as another key extension candidate to watch.

Mavericks’ Dereck Lively To Play For First Time In 36 Games

April 2nd, 2025 at 6:00pm CST by Alex Kirschenbaum

Mavericks center Dereck Lively II is set to return to action for a Wednesday night tilt against Atlanta, per a team press release (via Twitter).

Lively has missed 36 consecutive contests for the Mavericks. The second-year pro has been on the shelf since January 14 with a right ankle stress fracture.

Dallas head coach Jason Kidd told reporters that the 7’1″ big man will be operating on a 15-minute restriction, per Tim MacMahon of ESPN (Twitter link).

Ahead of the postseason, several previously ailing Mavericks are healing. Beyond Lively, fellow big men Anthony Davis and Daniel Gafford recently returned to the lineup.

Among the Mavs’ core rotation, only nine-time All-Star guard Kyrie Irving — arguably the team’s most important player — is out long-term, as he recuperates from surgery to address an ACL tear. Forward P.J. Washington is also out, for now, due to an undisclosed illness.

Before his injury, the Duke alum had taken over starting duties at the five from Gafford early in the season. It remains to be seen how Kidd will ultimately deploy his big man rotation with Davis, Lively and Gafford all having started at center for the team this year.

In his 32 healthy games for the team, including 25 starts, Lively has averaged 9.1 points, 7.8 rebounds, 2.6 assists, and 1.7 blocks per night.

At present, the Mavericks occupy the No. 9 seed in the competitive Western Conference. They’re just a half-game ahead of the No. 10 Kings and two games up on the No. 11 Suns.

Mavs’ Gafford Back In Action, Lively Close To Returning

April 1st, 2025 at 12:25pm CST by Luke Adams

Mavericks big man Daniel Gafford returned to action on Monday night against Brooklyn after missing 21 straight games due to a sprained knee and showed no signs of rust in his first game since February 10. In just under 19 minutes on the floor, Gafford racked up 17 points, seven rebounds, and a pair of assists.

It wasn’t all good news for Dallas, as the team dropped a very winnable game against a lottery-bound Nets team. Gafford also wasn’t entirely thrilled with his performance, though he said it felt good to be back in action, adding that he thought he improved over the course of the night.

“It was real important to me (to get back in the lineup). I’ve got a big heart for the game,” Gafford said, per Greg Riddle of The Dallas Morning News. “There were times when I was down, and the people around me kept me motivated. It was a bunch of mess-ups from me early on, but throughout the course of the game, it just started to feel kind of natural again.”

As dispiriting as the Mavericks’ loss was, it didn’t hurt them much in the play-in race, since Sacramento also lost on Monday. The Suns gained a half-game as a result of having the night off, but they have the NBA’s most difficult remaining schedule and will be without their top scorer for at least the next three games.

The 37-39 Mavs currently hold the No. 9 seed in the Western Conference, with a half-game lead on the No. 10 Kings and a 1.5-game cushion on No. 11 Phoenix. And after getting Gafford back on Monday, they should have another key contributor available soon — big man Dereck Lively, sidelined since January 14 with a stress fracture in his ankle, was listed as questionable vs. Brooklyn before being ruled out. Head coach Jason Kidd said the second-year center is “trending” toward returning this week, according to Riddle.

Assuming they have Anthony Davis, Gafford, and Lively available during the home stretch of the regular season, the Mavericks figure to lean pretty heavily on lineups featuring multiple big men. As Christian Clark of The Athletic writes, Davis said after Monday’s loss that it was the first time he has been part of a two-big lineup for an entire game and that he still needs to get used to it. However, he and Gafford are both excited about the possibilities.

“It’s an advantage we have, having two bigs,” Davis said, according to Eddie Sefko of Mavs.com. “They’re going to switch or blitz and with his ability to jump and put pressure on the rim, it’s going to be open.”

“The thing that excites me is when it comes to certain parts of the game defensively, we are going to go through the roof,” Gafford added, per Clark. “Offensively, I need to be in the right spot at the right time. It makes my job easier. I just have to get better at guarding guys on the perimeter.”
