The Dallas Mavericks are continuing to change their coaching infrastructure this offseason.
Dallas has already seen several assistant coaches on head coach Jason Kidd’s staff depart for greener pastures. Former longtime NBA stretch forward Jared Dudley, who had been working with Kidd for the previous four seasons, will now be Denver Nuggets head coach David Adelman’s lead assistant.
Former Mavericks assistant Sean Sweeney is defecting to serve as the associate head coach for the San Antonio Spurs under Mitch Johnson. Johnson had been working in an interim capacity following San Antonio coach Gregg Popovich’s early-season stroke, but Popovich eventually officially stepped down.
Another Dallas assistant, Alex Jensen, is now the head coach for the University of Utah Utes. Former player-turned-player development assistant coach God Shammgod is ditching the Mavericks for the Orlando Magic, following six years in Dallas.
The Mavericks pivoted, bringing in reinforcements with major pedigrees.
Dallas has promoted consultant Frank Vogel, who was the head coach on the title-winning 2019-20 Los Angeles Lakers (Kidd was his assistant), to an associate head coach role. Former Phoenix Suns and Toronto Raptors head coach Jay Triano and ex-Nuggets assistant coach Mike Penberthy have also been brought in. The Mavericks are reportedly considering longtime assistant coach Phil Handy.
Marc Stein of The Stein Line/Substack reports that a former Dallas special assistant is also moving on — but still staying in the broader Mavericks family.
I’m told Mavericks special assistant Shannan Lum is expected to join the @TexasLegends as an assistant coach after the Legends officially announced former Oakland U. sharpshooter Max Hooper as their new head coach.

Per Stein, the Mavericks’ G League affiliate squad, the Texas Legends, will be bringing in now-former Dallas special assistant Shannan Lum to serve as an assistant coach.
Lam will serve on the staff of the Legends’ new head coach, ex-Oakland University Grizzlies guard Max Hooper. After college, Hooper played sparingly for the New York Knicks’ NBAGL affiliate, the Westchester Knicks, in 2016-17 and 2017-18, but failed to crack the NBA.
