If the Boston Celtics are seriously considering entering the 2025–26 season with Xavier Tillman, Neemias Queta, and Luka Garza as their center rotation, then it may already be too late to stop the unraveling. With those three as Boston's primary options on the interior, protecting the rim is going to prove an extremely big challenge from the jump.
Things were always going to be more difficult after the Celtics incurred such big losses in free agency. Those transactions alone would have left the Celtics thinner on both ends of the floor. But considering the fact that Jayson Tatum is unlikely to step on the hardwood for all of next season gives Boston a monumental challenge for 2025-26.
