The Celtics selected Tennesee power forward Grant Williams with the No. 22 overall pick on Thursday night. The 20-year-old is a junior and is built like a tank at 6-foot-7. He has quite the pedigree after taking home back-to-back SEC Player of the Year honors but does not have much of a jump shot (32 percent from 3 on just 1.2 attempts per game). He's a great finisher at the rim and highly efficient around the basket, but serves as a bit of a tweener in the frontcourt. His size and ability to create on offense serves as his biggest questions but he's definitely got a high motor and stood out as one of the best defensive players in the nation this past season. Just how much that translates to the NBA game is the question.
