The Phoenix Suns will open their 2026-27 training camp on September 29, 2026, ahead of the new NBA season. The team is currently managing a significant setback with newcomer Mark Williams, who recently underwent surgery.
Why it matters
The Suns are entering the season aiming to improve upon their 45-win performance from the previous year. The team's depth and athleticism are under scrutiny following personnel shifts and an injury that could sideline a key rotation player for months.
Mark Williams averaged 11.7 points and 8 rebounds last season, while Collin Gillespie established a franchise record by sinking 232 made 3-pointers. The team must finalize its 15-player standard roster by October 19.

He is an NBA center who signed a three-year, $38-million contract with the Phoenix Suns.

Collin Gillespie
He is a guard who set a new Phoenix Suns franchise record with 232 made 3-pointers in the previous season.

Season Trajectory
The team enters the year attempting to solidify their standing within the highly competitive Western Conference playoff bracket. The squad's reliance on depth will be tested as they manage rotation changes to avoid falling into the lower half of the play-in tournament standings.
The absence of Mark Williams creates immediate vacancies in the frontcourt rotation that will impact team rebounding metrics. Fans and analysts should monitor the waiver wire and training camp performance of backup centers to identify potential production gaps in the early schedule.
The takeaway
The Suns face a challenging start to the season while navigating the recovery of a key frontcourt acquisition. Flexibility in the final roster construction will be essential to maintaining competitive depth throughout the long regular season schedule.
