Mavs Notes: Williams, Powell, Medical Staff, Camp

October 10th, 2025 at 10:03pm CST by Eli Cohen

With Kyrie Irving injured, fourth-year guard Brandon Williams is expected to take on a larger ball-handling role with the Mavericks behind D’Angelo Russell.

Williams has spent the past two seasons with Dallas, averaging 8.3 points and 2.3 assists per game and making 40.0% of his three-point shots in 33 outings last saeson. The 25-year-old played twice for the Mavs this offseason at Summer League, where he averaged 16.0 PPG and 4.5 APG and drew the praise of head coach Jason Kidd.

“I thought at the end of the summer, he was playing at a high level,” Kidd said, as relayed by Mike Curtis of the Dallas Morning News (Twitter link). “When he’s healthy, he’s a problem.”

Williams’ health has been a question mark as of late, as Kidd announced on October 1 that the guard sustained a hamstring strain that would keep him out for at least a week. When asked about his status for Saturday’s preseason game against the Hornets, Williams said that he’s “playing it day-by-day,” according to Curtis (via Twitter).

As for what Kidd expects when Williams returns to the floor, the head coach said: “Growth as always. Understanding time and score, who hasn’t gotten a shot, how are we playing on the offensive end. When we have the ball, you’re a leader so some of that leadership role is something that he’s going to have to show us again this year.”

We have more from the Mavericks:

Dwight Powell is the longest-tenured Maverick, having played the last 10-plus seasons in Dallas after a quick five-game start to his career in Boston. Having seen many iterations of the team, he’s excited about the season to come, writes Eddie Sekfo for NBA.com. “It’s one thing to be talented,” Powell said. “But you got to have that competitive edge and want to compete on every possession. Our ability so far to be able to do that in practice is a great sign for what’s to come in the season ahead. That’s something I’m very excited about.” With Daniel Gafford injured, Powell has a better chance to earn minutes early in the season than he will when the team is fully healthy, but regardless of his role, he’s ready to contribute any way he can. “I try my best,” he said. “Try my best to help any way I can, be a spark where I can and lead where I can. And find ways to help us be successful. That role’s going to change throughout the year. You just got to be ready for the opportunities.”
After facing a slew of injuries last season, most notably to Anthony Davis, Luka Doncic, and Irving, the Mavs overhauled their medical staff this season, writes Curtis. Curtis notes that last year’s team was one of the NBA’s most injured, losing 444 total man games. In the hopes of reversing that trend, the Mavs promoted Jana Austin from assistant athletic trainer to head athletic trainer and hired Geoff Puls from the Bulls as their head of strength and performance. They also let go of Dionne Calhoun, who had been with the team for 21 years. Johann Bilsborough, who was at the center of an in-depth article last season detailing the turmoil within the Mavs’ health and performance team, will oversee the staff for the second straight year.
One of the changes the Mavericks will have to deal with this season, especially while Irving recuperates, is adjusting to a more egalitarian style that relies less on a ball-dominant guard like Doncic, Sekfo writes. “In this league or any league as a coach, you got to be able to pivot with the roster you have,” Kidd said. “This is a different roster than I’ve had in the past. When you have players that I’ve had, you play to their strengths. This team is different. So to be able to be big and play with that type of pace is to our advantage.” Kidd noted that players like Russell and Klay Thompson will likely benefit from the team’s emphasis on pushing the pace.

Southwest Notes: Mavs, Aldama, Popovich, Pelicans

Mavericks general manager Nico Harrison is making major changes to the club’s health and performance team, according to reports from Marc Stein (Twitter link), Mike Curtis of The Dallas Morning News and Tim MacMahon of ESPN. Those changes include parting ways head athletic trainer Dionne Calhoun and athletic performance director Keith Belton, among others.

As MacMahon details, Calhoun has spent over two decades with the Mavericks and had been the team’s head athletic trainer since 2019. He was one of the last holdovers from the staff of former health and performance director Casey Smith, who was let go in 2023.

MacMahon previously published a lengthy story about the turmoil within Dallas’ health and performance director, as we relayed last month. That story included details on a “loud, heated confrontation” between Belton and director of player health and performance Johann Bilsborough over how the team was handling Dereck Lively‘s ankle injury. That incident spurred an HR investigation, according to MacMahon, who says Bilsborough remains employed by the team.

Here’s more from around the Southwest:

Damichael Cole of The Memphis Commercial Appeal previews Santi Aldama‘s upcoming restricted free agency, noting that the presence of solid frontcourt options like Jaren Jackson Jr., Brandon Clarke, and Zach Edey will give the Grizzlies some leverage in their negotiations with Aldama. However, the 24-year-old Spaniard has steadily improved during his four years in Memphis and his offensive skill set is an asset, Cole notes, so the team won’t necessarily be able to bring him back at a bargain rate.
In a feature story for ESPN.com, Baxter Holmes takes an in-depth look at the “unparalleled” legacy that Gregg Popovich will leave behind after coaching the Spurs for the better part of three decades. Holmes spoke to Steve Kerr, Jerry Colangelo, Mike Krzyzewski, and Adam Silver, among others, about the impact that Popovich had during his long run as the head coach in San Antonio.
Ahead of Monday’s draft lottery, William Guillory of The Athletic explores what the Pelicans‘ draft options will look like if they don’t have a shot at Cooper Flagg at No. 1 overall. Guillory breaks down some hypothetical scenarios in which New Orleans lands V.J. Edgecombe (at No. 4), Kon Knueppel (No. 5), and Jeremiah Fears (No. 7).

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.
