Xavier Tillman is making strides physically ahead of the 2025-26 NBA season, with significant improvement in his knee condition, according to The Athletic’s Jay King. With the Boston Celtics’ frontcourt reshuffled and key players like Jayson Tatum sidelined, Tillman may see a greater role in the lineup. While he remains a fringe option in standard fantasy leagues, Tillman’s improved health could provide value in deeper formats if granted increased playing time.
