DHJ Quick Take: Phil Handy Remains on Dalals Mavericks’ Coaching Staff

Phil Handy remains with the Dallas Mavericks as new head coach Dusty May fills out his coaching staff, Dallas Hoops Journal has learned.

  • What’s the headline news? Phil Handy will remain with Dallas as a player development coach under Dusty May.
  • Who else is joining? Garrett Temple and Joe Boylan have also joined the staff, while Willie Green is expected to join as a lead assistant.
  • Why does this matter? Handy’s continuity gives May, an NBA head coach for the first time, an experienced voice to help develop Dallas’ young core.
  • What’s next? Dusty May continues to add to his coaching staff.

DALLAS — Phil Handy remains with the Dallas Mavericks under new head coach Dusty May, sources told Dallas Hoops Journal. Handy, who has a close relationship with Kyrie Irving, provides May with a trusted, familiar voice as he begins his first season as an NBA head coach.

Handy joined the Mavericks’ staff in 2025 after previous stops with the Cleveland Cavaliers (2013-18), Toronto Raptors (2018-19) and Los Angeles Lakers (2019-24), winning an NBA championship in each city. He most recently served as head coach of the Mist Basketball Club in the Unrivaled League before returning to an NBA bench in Dallas.

With Cooper Flagg, Morez Johnson Jr., and the rest of the Mavericks’ young core needing individual development, retaining Handy keeps a proven developmental piece in place on a staff that is otherwise undergoing significant turnover.

Known Coaching Staff Changes

Frank Vogel, Popeye Jones and Mike Penberthy will not be part of May’s staff, sources told Dallas Hoops Journal. Vogel served as Dallas’ lead assistant under Jason Kidd, while Jones and Penberthy joined the staff in 2025, focused on defense and shooting development, respectively. Jones has since landed with the Orlando Magic, who officially announced him Monday as a member of new head coach Sean Sweeney’s staff.

Jay Triano will not be back with the Mavericks, sources said, and has been linked to the Portland Trail Blazers to reunite with new head coach Micah Nori on Nori’s first staff. The two worked together for years with the Toronto Raptors, where Triano first promoted Nori to assistant coach.

Jordan Sears will not return to the Mavericks, sources said. Sears is joining the Charlotte Hornets. Sears has been with the Mavericks organization for years, most recently as an assistant coach after two seasons (2023-25) as head coach of the Texas Legends, Dallas’ G League affiliate.

Eric Hughes, Keith Veney and Dru Anthrop will also not return, sources said. Hughes joined the Mavericks in 2023 and previously worked under Kidd with the Brooklyn Nets and Milwaukee Bucks. Veney, a former Marshall University standout who still holds the NCAA record for three-pointers made in a single game, had been with the organization in a player development role. Anthrop joined Dallas after working under Vogel with the Phoenix Suns in 2023-24, following earlier stints with the Los Angeles Lakers, Memphis Grizzlies and Orlando Magic.

New Additions to Coaching Staff

Joe Boylan joins the staff as head coach of the Mavericks’ Summer League team in Las Vegas and will be an assistant coach during the regular season. He previously worked with the Memphis Grizzlies, Golden State Warriors, New Orleans Pelicans, and Minnesota Timberwolves.

Garrett Temple, a 16-year NBA veteran, is joining May’s staff to transition from playing to coaching and Willie Green is expected to join May’s staff, Dallas Hoops Journal recently learned. Green spent four seasons (2021-25) as head coach of the New Orleans Pelicans, following two NBA championships as an assistant coach with the Golden State Warriors.

What’s Next

May, making the jump from college to the NBA for the first time, is expected to continue adding to his staff.

One name to watch is Josh Broghammer, who worked closely with Flagg and coached last year’s Summer League team. A return to the Mavericks for the assistant coach has not been ruled out, sources said.
