Pruitt is just getting started. His opportunities should continue to increase and if he does well with them he's there. I wouldn't worry about him getting those opportunities, I think they'll come, we just need some patience while Doc gets comfortable with him. We'll see how he does once he gets a consistent amount of minutes and games and what type of role he can play for the club this season.
I don't think Scal or O'Bryant are answers to anything the Celtics. Scal is playing about as much this team can get away with already, he just doesn't contribute enough when on the floor to get longer court time. Scal is a serviceable player but only at the role he's playing, or preferably even less. I don't like O'Bryant's defense or soft interior play.
I'd like to see Powe play some more minutes, in particular more minutes than Davis. See how he does playing 18-19 minutes a night instead of 15.
