The Boston Celtics were devastated when Jayson Tatum tore his Achilles in Game 4 against the Knicks in the second round of the playoffs. Not only did it end any chance of the Celtics completing a comeback in that series,

Celtics assistant coach Sam Cassell is optimistic that Tatum will return to his All-Star form after he rehabs from his injury.

Tatum had 42 points, eight rebounds, four assists, four steals and two blocks in Game 4 before his tendon gave out on him, doing everything possible on both ends of the court to prevent the Celtics from falling into an ominous 3-1 deficit.
