Tillman is a defensive-driven big whose career in Boston hinges on durability and a credible jumper. His switches and turnover creation give him late-round upside, but without a reliable three-point shot or ball-handling, his role remains fringe. A league-average jumper could unlock minutes and two-way value behind a reshuffled frontcourt.

Tillman competes with Garza for seconds after Queta, offering potential as a defensive anchor and energy big. His upside rests on minutes and defensive IQ, with fantasy value depending on role clarity and second-unit opportunities.

Tillman’s presence provides a versatile, multi-positional option inside. His ability to guard multiple frontcourt matchups and provide efficient scoring off dumps can stabilize Boston’s interior, contributing to rebounds, blocks, and steady offense.

Xavier Tillman Sr. currently wears jersey No. 26 for the Boston Celtics. He was drafted 35th overall in 2020 and has averaged 2.2 points and 1.8 rebounds per game since joining the team from Memphis.

Tillman has had limited playing time this season, making him a candidate for trade as the Celtics explore options to acquire Yabusele.
