Xavier Tillman joined the Celtics late last season after being acquired from the Memphis Grizzlies. Limited by a knee injury initially, he had minimal postseason use but made a notable impact with a clutch three-pointer in the NBA Finals. Standing at six-foot-eight, Tillman offers a unique skill set, including the ability to shoot from distance, which could make him a valuable asset as the season progresses. His solid defensive capabilities and versatility position him as a candidate for increased minutes, especially as the team navigates the absence of Kristaps Porzingis. With the preseason providing an opportunity for experimentation, Tillman’s performance could be pivotal in solidifying his role within the rotation.
