They're different players but it's an interesting comparison because while Hauser has a plus-skill (3-point shooting), the reason he was in the Celtics' playoff rotation is because he's turned himself into a decent defender. Nobody's focusing on it in Summer League, but we know there were games last season where Cam got roasted a bit. I have no doubt he'll put the work in to be as good an on-ball defender as possible, so hopefully he can have as good if not a better career than Hauser, who, unlike Cam, can only play off the ball.
