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).
