Mark Williams' Shoulder Surgery Turns Phoenix's Center Plan Upside Down

The Phoenix Suns spent the summer building a roster designed to take another step after a 45-37 season and a playoff cameo. Barely a week before training camp, that plan took its first real hit: starting center Mark Williams tore the labrum in his left shoulder during a scrimmage, underwent surgery, and is now out for an extended period — with reporting suggesting a possible return around the All-Star break.

That's a substantial loss for a team that doesn't have much margin for error. In 2025-26, Williams appeared in 60 games and averaged 11.7 points, 7.9 rebounds and 0.9 blocks in 23.6 minutes per night, while shooting 64.4% from the floor. He was the vertical threat and defensive anchor that let Phoenix's perimeter group function. The Suns' power rating already reflects his absence — they sit 18th with a -0.895 neutral-court score, and that figure is docked 2.68 points for injuries to Williams, Collin Gillespie and Jordan Goodwin. The healthy version of this team is meaningfully better than the number the market sees.

Phoenix's Response: Duop Reath and a Committee

The front office moved quickly, signing center Duop Reath to a one-year deal. Reath, 30, is a stopgap, not a savior — he averaged 2.9 points and 1.2 rebounds in just 8.0 minutes across 32 games last season. The one thing he offers is shooting: he hit 41.8% from three on limited attempts, which fits a Phoenix offense that wants to play five-out at times.

The bigger question is how head coach Jordan Ott distributes minutes. Khaman Maluach, the 7-footer who logged only 8.9 minutes a game as a rookie, is the long-term answer but shouldn't be thrown into the deep end. Oso Ighodaro is the steadier short-term option — he played all 82 games last season at 22.1 minutes, shooting 65.3% from the field while grabbing 5.1 rebounds a game. He's also a sub-50% free-throw shooter with zero three-point makes, so he's a finisher and screener rather than a spacer.

That trade-off matters. Without Williams, Phoenix may lean on smaller, switchier lineups with Miles Bridges and Ryan Dunn absorbing frontcourt minutes. Dunn has the defensive tools but averaged just 5.8 points on 45.3% shooting last year. It's a collective solution to a problem that used to have a single, reliable answer.

What It Means for the Season

The Suns' rotation was already crowded with questions. Devin Booker remains the engine — 26.1 points and 6.0 assists per game in 2025-26 — and Bridges (17.1 points, 5.8 rebounds, 77 games last season) was brought in to raise the offensive ceiling. Jalen Green, who managed just 32 games a year ago, is another player the team needs healthy and productive.

Losing Williams doesn't sink a season in September, but it changes the math. The market currently prices Phoenix around a 40.5 win total with roughly a -120 implied favorite to make the playoffs — an expectation that assumes a functional interior. If the committee holds, the Suns can survive until Williams returns. If it doesn't, the rebounding and rim-protection issues that plagued stretches of last season will resurface against a loaded Western Conference.

The most encouraging part of Phoenix's offseason was depth. That depth is now being asked to do something it wasn't built to do: replace a starting center for half a season. How well Ott manages that will determine whether this team competes for a playoff spot or spends the winter chasing one.
