Dereck Lively

Mavs Exercise 2026/27 Option On Dereck Lively

October 20th, 2025 at 2:54pm CST by Luke Adams

The Mavericks have formally exercised their fourth-year option on Dereck Lively II‘s rookie scale contract, the team announced today (via Twitter).

The move, which had been expected, locks in Lively’s $7,239,130 salary for the 2026/27 season, putting him on track to become eligible for a rookie scale extension during the 2026 offseason. If he and the Mavs don’t work out a new deal at that time, he’d reach restricted free agency in 2027.

A 7’1″ center, Lively has averaged 8.8 points, 7.1 rebounds, and 1.5 blocks in 23.4 minutes per game for Dallas during his first two years in the league, making 72.9% of his shot attempts from the floor.

While the 21-year-old has shown plenty of promise early in his NBA career, staying on the floor has been a challenge — injuries have limited him to 91 total appearances (71 starts), including just 36 (29 starts) in 2024/25. He underwent a procedure to clean up bone spurs in his right foot in July, but was available during the preseason and should be ready to go when the team’s season tips off on Wednesday vs. San Antonio.

Decisions on rookie scale options for the 2026/27 season are due on October 31. We’re tracking all of them right here.

Mavs Notes: Flagg, Chemistry, Rebounding, 2026 Preseason

October 12th, 2025 at 9:57pm CST by Eli Cohen

There are many reasons that Cooper Flagg was the obvious choice for the Mavericks with the No. 1 pick in the 2025 draft — he’s a high-level defender, a talented shot-maker, and an underrated passer. However, there’s one trait of his that head coach Jason Kidd is most impressed by, according to Eddie Sefko of NBA.com: his toughness.

“His willingness to compete at a high level and his willingness to be uncomfortable,” Kidd said when asked what parts of Flagg’s games stood out early on. “He absorbs that. I think those are his superpowers. His winning DNA – he stood in line a little bit longer to get that at a very high level. He’s all about winning.”

Kidd spoke excitedly about the potential of Flagg and young center Dereck Lively II to grow together, as well as their ability to impact winning in the near-term. That quality, along with the toughness, is what Kidd values the most in Flagg.

“It’s not about how many shots he gets or how many minutes or how many times he touches the ball,” Kidd said. “He’s about the team. He’s about winning. That’s the biggest thing that stands out — he competes to win.”

We have more on the Mavs:

Through two preseason games, Flagg is still working on establishing chemistry with his new teammates and continues to search for the best ways to complement fellow frontcourt star Anthony Davis. “I gotta find ways to help AD more,” he said, per The Dallas Morning News’ Mike Curtis (Twitter video link). “Play off him a little better. Help him impact the game when he’s posting up, getting his isos and whatnot. It’s been huge just trying to fit together. That’s what the preseason is for, just for us to come out and get that real game minutes together and kind of gel.“
While Flagg had five turnovers in Saturday’s 120-116 loss to the Hornets, the Mavs aren’t concerned with him experimenting and finding the limits of his play-making during the preseason, writes Sefko. Of more concern is the fact that the team was badly beaten in the rebounding battle, with the Hornets pulling down 54 boards to the Mavs’ 37. Given Dallas’ jumbo-sized lineup of Flagg, Davis, and Lively, the team expects to be one of the best rebounding squads in the league, Sefko writes, and it will likely have to be, given the shooting sacrifices that such a lineup would entail. Sekfo notes that Kidd addressed the issue, saying it will be a point of emphasis for the rest of the preseason.
The Mavs’ owner, Patrick Dumont, was present for the matchup between the Nets and Suns in Macao, reports Brad Townsend of the Dallas Morning News (via Twitter). Dumont was a part of the effort to rebuild the NBA’s relationship with China, according to Townsend, who believes there’s a good chance the Mavs will play in China during the 2026 preseason. Marc Stein (Substack link) has heard the same thing.

Mavs Notes: Flagg, Starting Five, Russell, DSJ

October 7th, 2025 at 10:13am CST by Luke Adams

No. 1 overall pick Cooper Flagg showed off his versatility in his preseason pro debut on Monday, according to ESPN’s Tim MacMahon. The Mavericks forward scored 10 points, grabbed six rebounds, and handed out three assists in just 14 minutes of action, taking on some point guard responsibilities against the defending champion Thunder.

As MacMahon notes, Flagg also showed off his defensive ability early in the first quarter when he stepped in from the weak side to block a Isaiah Joe layup attempt, which led to a fast-break basket for Dallas.

“You got to see the defensive side, you got to see the play-making and then the scoring,” head coach Jason Kidd said. “He was really, really good.”

While Flagg’s scoring and play-making may generate more highlights during his rookie season, the Mavericks are bullish on what he can do defensively, with Anthony Davis suggesting during training camp that his new frontcourt partner can “defend one through five,” as Grant Afseth of Dallas Hoops Journal relays.

“We’re going to put him in situations where you have to guard maybe the best wing — have to guard (Kevin) Durant or Jimmy Butler or these guys,” Davis said of Flagg. “And we have enough confidence in him to go out and send him out there and be able to guard those guys. But he’s also got help on the back line with the other four guys on the floor.”

We have more on the Mavs:

As Christian Clark of The Athletic details, the starting lineup that Kidd used on Monday – Flagg, Davis, D’Angelo Russell, Klay Thompson, and Dereck Lively II – seems likely to be the one the team will deploy when the regular season begins. That means forward P.J. Washington, who started 56 of his 57 games last season, figures to come off the bench as long as the rest of the frontcourt is healthy and available.
Russell made a strong impression in training camp, earning kudos from Kidd for fitting in quickly and being willing to speak up and use his voice despite being a Mavs newcomer, as Afseth writes for Dallas Hoops Journal. The Mavs’ head coach had more praise for the point guard following a preseason opener in which he scored five points and distributed a team-high five assists in 15 minutes of action. “I thought he did a great job finding guys,” Kidd said, per Mike Curtis of The Dallas Morning News. “I thought his defense was really good. Oklahoma City puts a lot of pressure on you on the one-on-ones and I thought he did a really good job defensively … I thought D-Lo did a really good job.”
Dennis Smith Jr. didn’t play in Monday’s game, but Kidd appreciated the intensity the veteran guard brought to training camp, according to Afseth at RG.org. Smith, who is with the team on a non-guaranteed contract, says he appreciates the opportunity to compete for a roster spot in Dallas. “I’ve got to come out and put my best foot forward every day,” he said. “If that happens to be what the team needs, that makes it even better — and it is. So I’m in a good spot.”

Mavericks Notes: Flagg, Davis, Washington, Lively

October 2nd, 2025 at 1:33pm CST by Rory Maher

No. 1 overall pick Cooper Flagg enters a unique situation with the Mavericks, who have two other former top picks on the roster in Anthony Davis and Kyrie Irving, plus a frontcourt with plenty of talent and depth. The 18-year-old forward says he’s going to use the versatility that helped him become an elite prospect, writes Grant Afseth of DallasHoopsJournal.com.

“For myself, it’s just about being me — going through it, not changing for anybody, impacting the game in a lot of ways, and doing whatever I can to impact winning,” Flagg said at media day. “Coach (Jason) Kidd and I have talked about being versatile. We’ve got a bunch of guys who can do a lot of different things, so we want to use that to our advantage.”

Flagg, who won virtually every college player of the year award last season for Duke, is open about his expectations for 2025/26.

“I’d like to be Rookie of the Year,” Flagg said, per Afseth. “As a team, the goal is obviously to win a championship. But like I said earlier, if I stay true to myself and what got me here, the personal goals will work themselves out.”

Four-time NBA champion Klay Thompson believes Flagg has all the right ingredients to fulfill his potential, Afseth notes.

“Cooper can be as good as he wants to be,” Thompson said. “He’s got all the tools — height, athleticism — but what I love most is that he’s receptive to information and he wants to work. When you combine that with his athleticism, he can be special.”

Here’s more from Dallas:

The Mavs only had a 1.8% chance of winning the draft lottery and Davis admitted he wasn’t watching the unlikely occurrence in May. Still, he was thrilled with the outcome, according to Christian Clark of The Athletic. “He’s a hell of a talent,” Davis said of Flagg. “He can do everything on the floor. It was a great moment for us.”
Davis says his goal for this season is the same as it was when he was shockingly traded to Dallas in the Luka Doncic blockbuster in February, as Afseth writes for Dallas Hoops Journal. “Same as last year at my press conference: my goal hasn’t changed. I want to bring a championship here,” Davis said. “We’ve got a good team. The key is health — staying healthy. I’m happy and excited to be here, and I want to win here.”
The 10-time All-Star big man is listed at 268 pounds for training camp, 15 pounds heavier his listed weight last season. Davis says he isn’t concerned, explaining that’s not unusual for him to enter camp above his playing weight because he typically loses 10-12 pounds during the season and is feeling “great,” tweets Tim MacMahon of ESPN.
According to Clark, forward P.J. Washington made it clear he hopes to spend the rest of his career with his hometown team. Washington signed a four-year, $89MM extension last month. “It’s always been home for me,” Washington said. “I’m just blessed to be here. I’ve always wanted to be here. Hopefully, I end my career here.”
Center Dereck Lively II was limited to just 36 games last season after playing 55 contests as a rookie. He’s determined to be available more often in year three following offseason ankle surgery, per Afseth of Dallas Hoops Journal. “I want to stay healthy—that’s the biggest (goal),” he said. “From there, I want to keep growing as a defensive anchor. Be somebody my teammates trust to call things out, protect the rim, and cover for them.” Lively will be on a minutes restriction to start the season and he’s happy with the team’s plan. “Honestly, I just take whatever comes,” the 21-year-old said. “If it’s 24 minutes, 20 minutes, whatever the coaches need from me, I’ll give everything I have in that time. I’m just focused on playing the right way and building myself back up.”

Mavs Notes: Starters, Kyrie, Smith, Robinson-Earl, Coaches, Lively

September 29th, 2025 at 10:20pm CST by Alex Kirschenbaum

The Mavericks made one very significant roster addition over the summer, drafting No. 1 pick Cooper Flagg out of Duke. But the club’s starting five has yet to be determined heading into training camp, per Mike Curtis of The Dallas Morning News (Twitter link).

“This is competition,” head coach Jason Kidd said. “We’re going to look at a lot of combinations.”

Kidd has indicated that everyone aside from All-Star guard Kyrie Irving is expected to fully participate in practice, tweets Christian Clark of The Athletic. For now, free agent signing D’Angelo Russell is expected to start in Irving’s stead.

There’s more out of Dallas:

Irving continues to improve from the ACL tear he suffered last March. Kidd, however, offered a measured take on his recovery to date, per Tim MacMahon of ESPN. “He is doing quite well, as we can see, but he’s not ahead of schedule, and so let’s not say that,” Kidd said. “That’s unfair to him and to the Mavs because it’s not true. Is he on schedule? It looks like it.” Mavs president of basketball operations Nico Harrison had suggested in July that the star guard was “ahead of schedule” in his rehab process.
New Mavericks additions Dennis Smith Jr. and Jeremiah Robinson-Earl signed non-guaranteed Exhibit 9 agreements, per Keith Smith of Spotrac (Twitter link). The agreements protect the team in the event that either player sustains an injury in training camp or the preseason and don’t count against the cap unless they carry over to the regular season.
Kidd weighed in on Dallas losing assistant coaches Sean Sweeney, Jared Dudley, and Alex Jensen to other teams this summer, Curtis tweets. “The guys who left will be missed,” Kidd said. “Sweeney, Duds and Alex… It’s a compliment that we must be doing something right. Not wrong.”
Third-year Mavericks center Dereck Lively II indicated during his media day session that he has grown this summer, according to Marc Stein of The Stein Line (Twitter link). Lively, who was listed at 7’1″ last season, claims he is currently 7’2″ or 7’3″.

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.

August 4th, 2025 at 6:14pm CST by Dana Gauruder

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.”
