3 Boston Celtics who could be goners in the offseason if they win it all

Xavier Tillman Sr.

If the Celtics can only bring one big man back, it'd likely be Kornet. Xavier Tillman Sr. couldn't find the floor for the first few games after Porzingis went down and is undersized for the 5. His prospects of returning don't look good unless he has a lukewarm free-agent market.

Tillman has been a great locker room fit and has formed a bond with Al Horford, who will eventually need to be replaced in the rotation once he rides off into the sunset. Assuming that isn't this offseason, there will only be so many roster spots to dedicate to the 5 with Neemias Queta owning a team option. With the luxury tax growing more and more punitive every year, the front office has to start operating on the tightest of budgets.

Tillman's limited offensive skillset doesn't work on a team whose strength is 1-5 versatility on both ends of the floor. Not at anything but a near-minimum deal, anyway. The Cs winning the championship boosts his value beyond that, so prepare for a reality where Tillman is priced out of Boston whether or not Kornet comes back.
