Mavericks Training Camp Wrap-Up: Injuries, Standouts, and Depth Chart Battles After a Week in Vegas

The Dallas Mavericks wrapped up their week-long training camp at the University of Nevada, Las Vegas (UNLV) on Friday, a critical stretch of preparation as they gear up for the upcoming season.

One of the main storylines was Klay Thompson’s first exposure to the Mavericks’ system, along with the adjustments that other newcomers like Naji Marshall and Quentin Grimes are making as they settle into their roles.

The Mavericks also dealt with key injuries and competitive roster battles that tested the depth and versatility of the team. Reflecting on the week’s progress, head coach Jason Kidd expressed satisfaction with the energy and execution throughout camp.

“It was a great week,” Kidd said. “We got a lot of stuff in, and the energy was really high. I thought the guys competed and got better each day, which is all we can ask for.”

Spencer Dinwiddie, who stepped into a larger role during camp, echoed Kidd’s sentiments, noting the detailed work the team put in during two-a-day practices.

“It’s been great,” Dinwiddie said. “A couple of two-a-days. We’ve been doing a lot of installing on both offense and defense—some zone concepts, really everything. One of the best things about working with Coach Kidd and the staff is their attention to detail. They give you a lot of information.”

As the Mavericks conclude their time at UNLV, they shift their focus to refining player roles and cultivating team chemistry ahead of the upcoming regular season.

Here’s everything you need to know from Las Vegas:

Dallas Mavericks Injury Updates: Danté Exum and Luka Dončić Sidelined

One of the more significant developments late in camp came on Friday when the Mavericks announced that Danté Exum sustained a right wrist injury. Exum is currently undergoing evaluation, and more information will be provided when available.

This news comes while Luka Dončić recovers from a left calf contusion that has kept him out of practice, meaning he will miss Monday’s preseason opener against the Memphis Grizzlies.

Exum was becoming increasingly regarded as a key bench piece for the Mavericks, with the potential to play a pivotal role in their backcourt rotation. He was expected to provide critical depth behind Dončić and Kyrie Irving, with Spencer Dinwiddie possibly slotting in as a third point guard.

However, with Exum now sidelined, the short-term reality shifts. Dinwiddie and Jaden Hardy will be expected to step up in his absence. Jason Kidd emphasized the importance of depth and how players have responded well to these early challenges.

“The depth of our team, when you look at Spencer, definitely helps us,” Kidd said. “He gives us options that we might not have had before. But we’ve had him before, so we know what he’s capable of doing.”

Dinwiddie, who returned to Dallas this offseason, is poised to take on a larger role with Exum sidelined. Meanwhile, Hardy has impressed during camp, with Kidd highlighting his growth on both ends of the floor.

“Hardy’s been great this week,” Kidd said. “Offensively, he’s making plays, scoring, and defensively, he’s competing at a high level. We look for him to continue that form.”

However, the absence of both Exum and Dončić complicates the Mavericks’ plans to implement new offensive concepts, particularly those designed to integrate Dončić more off the ball. With Klay Thompson’s arrival, there is an opportunity for a fresh dynamic, as Kidd has indicated the team’s intention to reduce Dončić’s workload as the primary ball-handler.

“This offseason was short and sweet, so I didn’t give him much. I wanted him to relax,” Kidd explained to Marc Stein of DLLS. “I think that would make him stronger. We’ll see what he says. I know he loves the competition, but sometimes the point guard can start the offense in different spots on the floor.”

Dončić is an elite high-volume pick-and-roll and isolation player who consistently commands blitzes and draws help rotations with his ability to create off the dribble. Whether it’s launching his signature step-back three-pointer or penetrating the paint to finish or create for a teammate, the threat he poses commands an incredible amount of defensive attention—opening up his teammates. Integrating Thompson could alleviate some of that pressure, but without Dončić on the court, the team faces a delay in refining these strategies.

With Dončić sidelined, the opportunity to explore these adjustments and maximize Thompson’s off-ball movement will be limited. Although Kidd remains optimistic, stating there is “no concern” about Dončić’s long-term status ahead of the regular season, the team’s ability to fully implement their evolving offensive strategies may be temporarily stalled.

Klay Thompson’s Leadership and Integration

This week marked Klay Thompson’s first opportunity to work within the Mavericks’ system, and he has already made a significant impact. Known for his off-ball movement and elite shooting, Thompson creates space for others.

Kidd praised Thompson’s leadership, noting, “Klay doesn’t say a whole lot, but when he does, it means something. His actions speak volumes. He’s fully committed, taking every rep seriously, and that sets a great example for our young guys.”

Thompson has fully bought into the team’s offensive schemes and is eager to complement Dončić and Irving. His presence allows the Mavericks to experiment with new looks using off-ball actions, and Kidd pointed out that Thompson’s ability to pull defenders away will make the offense even more dangerous.

“Klay’s gravity is huge,” Kidd said. “He draws defenders and opens up space for Luka, Kyrie, and the rest of the guys. We can experiment with different looks, and Klay’s off-ball movement gives us a lot of options.”

Thompson’s role as a motion shooter is a natural fit within the Mavericks’ offensive framework. During Tim Hardaway Jr.’s stint, the team effectively utilized various off-ball actions, including wide pin-downs, middle pin-downs, Stack pick-and-rolls, and double-drag plays—along with Veer action and Wide actions in semi-transition. Thompson mastered all of this and more during his time with the Golden State Warriors. His experience and skill set open the door to expanding the Mavericks’ offensive repertoire, allowing for more dynamic plays and greater versatility on the court.

Thompson himself stressed the importance of training camp as he works to get fully adjusted.

“Training camp and the preseason is so important for me to get adjusted to this system,” Thompson said. “There are definitely some new things for me to pick up, but I’m excited to fit in with Luka and the guys. It’s going to be really fun.”

Dereck Lively II Displays His Growing Game

Dereck Lively II has emerged as a standout during training camp, competing for the starting center role with Daniel Gafford. Lively, entering his second season, has made noticeable improvements in his post-up game, footwork, and defensive presence. He has also flashed potential as a floor spacer, an added dimension that could benefit the Mavericks’ offense.

Kidd has been impressed with Lively’s overall development, particularly his ability to finish with both hands in the post.

“He was great. He’s another one ready to go. He was there with the first group; in the post, there were a lot of post-ups. He displayed something he’s maybe added here,” Kidd said after the first day of camp. “A lot of us were able to see that he finished with both his right and left [hands], and that’s something that hopefully can give us another weapon.”

On the second day of camp, Kidd continued to highlight Lively’s energy and shooting ability from beyond the arc.

“Yeah, I think he’s done great. His energy has been incredible. He’s ready to go and has really worked on his game—you can see it,” Kidd added. “His energy and spirit are great, and he’s shooting the three well. His post-up game is strong, and he’s just doing everything at a high level with that starting group.”

Teammates have also taken notice of Lively’s improvement. Quentin Grimes commented on how his work over the summer has paid off, especially in his ability to finish around the basket.

“We saw, probably yesterday, a couple of pin-ins, ducking into the post, a couple of right-handed hooks,” Grimes said. “You can tell he definitely worked on his game this summer for sure and he’s going to be a big help for us this season.”

Defensively, Lively’s shot-blocking and presence in the paint have been key. Naji Marshall praised his ability to protect the rim and his versatility on both ends of the floor.

“Unbelievable. Big presence, obviously. He clogs up the paint, he’s a lob threat, and he plays on both sides of the ball,” Marshall said. “I’m really looking forward to playing with him. It’s going to be rock and roll for sure.”

The competition for the starting center job remains open, but Lively’s all-around growth, including his potential to stretch the floor, has solidified his case for significant playing time.

Naji Marshall’s Two-Way Versatility Shines

Naji Marshall has been another standout throughout camp, impressing both coaches and teammates with his two-way play. Known for his defensive skills, Marshall has also displayed an expanded offensive game, knocking down pull-up jumpers, floaters, and three-pointers with consistency. His performance earned praise from Klay Thompson after Day 1 of camp.

“Naji was incredible,” Thompson said. “The guy was making floaters, pull-ups, and just played really well. He even scored a couple of times on me. His jumper was fluid, and his mid-range game was nice. Naji really impressed me.”

Marshall, who signed a three-year deal with the Mavericks, is ready to contribute in any way the team needs. He’s emphasized doing the dirty work on both ends without sacrificing being an aggressive threat offensively.

“I’m here to do whatever the team needs—defense, offense, energy,” Marshall said. “It’s been great getting adjusted and setting the tone early.”

Last season with the New Orleans Pelicans, Marshall shot a career-best 38.7% from three-point range. Now, playing alongside Dončić, Irving, and Thompson, he expects to find even more open looks and continue his upward trajectory.

“All the attention is going to be on them, so it’s going to leave me open to knock down shots,” Marshall said. “I’ll probably shoot a lot more open shots than I ever have before, and that’s always a plus.”

Marshall’s improved shooting, combined with his ability to attack closeouts, has added another dimension to his game.

“Being able to knock down shots consistently lets me play my natural game,” Marshall explained. “Adding that three-point shot just made me more unstoppable.”

Marshall’s energy, defense, and offensive versatility have made him a key figure in camp, and his presence is expected to be crucial in the Mavericks’ rotation.

Quentin Grimes Continues a Smooth Transition with the Dallas Mavericks

Quentin Grimes has quickly made his presence felt, demonstrating his ability to adapt to his new team’s system and bringing his well-rounded skill set to the forefront. Known for his defense and versatile offensive game, Grimes has been adjusting smoothly and earning praise from teammates and coaches alike.

Grimes has embraced the Mavericks’ positionless basketball approach, which allows more freedom on the court for all players, and he’s excited about how that impacts his role in the team.

“Oh, it’s been great. It’s been super fun, super energetic. Everybody’s energy has been on a 10 every day, so it’s been a lot of fun, honestly,” Grimes said. “There’s a lot of freedom out there on the court, kind of positionless basketball with the players we have. It’s been fun learning a couple of new concepts they do differently here compared to New York.”

With superstars commanding so much attention, Grimes is in a position to take advantage of open shots and play with a free mindset.

“All the attention is going to be on them, so it’s going to leave me open to knock down shots,” Grimes said. “I’ll probably shoot a lot more open shots than I ever have before, and that’s always a plus.”

Offensively, Grimes’ ability to space the floor will be vital for the Mavericks. With Dončić and Irving drawing defenders, Grimes has an opportunity to thrive in catch-and-shoot situations. He has also been learning from Thompson, one of the best shooters in NBA history. Grimes is taking every chance he can to absorb Thompson’s wisdom, whether it’s shooting tips or learning how to move without the ball.

“I’ve been talking his ear off the whole time,” Grimes said of Thompson. “I’m with him every day, shooting after practice. He’s been a really good mentor, giving me tips on my shot and how to get easier shots off pin-downs. There’s a reason they call it the ‘Klay action.’ Learning from one of the best shooters ever is only going to elevate my game.”

As Grimes continues to adjust, his defensive acumen is also standing out. His ability to guard multiple positions and his defensive IQ have been key attributes as the Mavericks work on solidifying their rotation. Grimes is also excited about how his versatility complements the star power around him. His presence on both ends of the court will be crucial for Dallas as they look to maximize their depth and positional flexibility.

“I’m just here to fit in and play my role, whether it’s defense, offense, or bringing energy,” Grimes said. “With the talent we have on this team, it’s going to be a lot of fun.”

Other Standouts: P.J. Washington and Jaden Hardy Shine

P.J. Washington and Jaden Hardy have been two of the most impressive performers, particularly during Day 3 of training camp, earning praise from coaches and teammates.

Washington has set ambitious goals this season—aiming to make an All-Defensive Team and shoot 40% from three-point range. His performance in camp so far has earned him high marks from Kidd, who believes Washington is ready to take the next step after shooting 32.7% across 95 combined performances last season.

“Those are all realistic goals for him, and they’re things he can control,” Kidd said. “Defensively, he’s going to compete against the best offensive players, and when it comes to shooting, 40% or higher is definitely within reach. He’ll have a lot of open shots, and he’s put in the work.”

Kidd also wants to see Washington step up as a playmaker, giving him the freedom to initiate the offense more frequently, especially in transition situations. By having wings initiate the offense, the Mavericks can leverage their best offensive players from different spots on the floor, which is an intended goal with Dončić.

“For P.J., it’s about continuing to build on what he’s been doing. Last year, he shot the ball well, played defense, and contributed in the post. Now, the next step for him is being able to get the rebound and not always look for Luka or Kyrie. We trust that he can play-make too,” Kidd explained.

Washington’s ability to fill multiple roles—whether as a scorer, defender, or secondary playmaker—has made him a key piece for Dallas. His impact was also highlighted by Dinwiddie, who has seen firsthand what Washington brings to the team.

“P.J. was really good in open runs leading up to camp,” Dinwiddie said. “He’s been solid so far.”

Hardy has also been one of the standout performers in camp. Known for his scoring ability, he has continued to impress in typical ways, but also with his playmaking. However, it’s his defensive improvement that has stood out to the coaching staff.

“Hardy’s been great this week,” Kidd said. “Offensively, he’s making plays, scoring, and defensively, he’s competing at a high level. We look for him to continue that form.”

Hardy’s scoring ability is well-established, but his commitment to becoming a more complete player has been expressed throughout camp. His defensive effort and attention to detail have been praised, and the team hopes he’s emerged as a player capable of contributing on both ends of the floor to provide a spark off the bench.

Team-Building in Las Vegas: Mavericks Attend Aces Playoff Game

The Mavericks wrapped up their week-long training camp in Las Vegas, but the team’s time off the court proved just as valuable for building chemistry. The decision to hold camp in Las Vegas was driven largely by the team’s new majority owners, Miriam Adelson and Patrick Dumont, who reside in the city.

Kidd explained that gathering in Las Vegas was about preparing for the season on the court and strengthening relationships within the organization.

“Our ownership group, that’s the main reason we’re here,” Kidd said of holding camp in Las Vegas. “Our new owners live here, and we had a nice dinner at their home. So training camp has started on the right foot.”

The team gathered for a dinner hosted by Adelson and Dumont, which Kidd described as a meaningful opportunity for camaraderie.

“When you talk about the Adelson family, they want to win. They want to win championships,” Kidd said. “What they’ve done here in half a year—we go to the NBA Finals, and we believe that we got better this summer. Hopefully, we can find our way back to the Finals.”

Thompson echoed Kidd’s sentiments on the importance of team bonding during camp. “It was great to be welcomed into their home,” Thompson said of the dinner with the Adelsons. “The food was delicious, and the artwork in that house was really impressive. It was fun to see.”

In addition to team dinners, the Mavericks took time to enjoy Las Vegas’ vibrant sports scene. Several players and staff, including Kidd, Dončić, Lively, and Irving, attended Game 3 of the WNBA semifinal series between the Las Vegas Aces and New York Liberty. The group, seated courtside, drew applause from the crowd when featured on the Jumbotron. Irving even shared the moment sitting next to WNBA legend Cheryl Swoopes, underscoring the support for women’s basketball.

By utilizing Las Vegas as a hub for team-building activities, from dinners with ownership to supporting other professional athletes, the Mavericks were able to deepen relationships and set a strong foundation for the upcoming season. The team still holds the benefits of last season’s 12-day international preseason trip with stops in Abu Dhabi and Madrid in high regard, especially for how it helped foster camaraderie and build lasting connections within the roster.

What’s Next?

With training camp finished in Las Vegas, the Mavericks return to Dallas on Saturday, where they will host Fan Jam at the American Airlines Center on Sunday. This event will give fans a closer look at the team before the preseason begins.

In light of the injuries and ongoing need for clarity throughout the depth chart, the upcoming preseason is important for the Mavericks, providing opportunities for players to compete for roles and build chemistry. As the regular season opener against the San Antonio Spurs approaches on October 24, the team is focused on solidifying its rotation and maximizing the potential of its new additions.
