Comparing Sullinger to past Celtics:
He looks like he has a shot that can become as good as Bass over time. He's got a nice nose for the ball and scoring, like Leon Powe. Yet he has many more offensive moves than Powe.
He has a nice feel for the game. Thats about all he has in common with Davis. Davis could probably move his feet better. But Sullinger has better rebounding, shooting, low post skills.
