I like Pruitt as well, If you leave him open he can shoot, if you overplay him he can go inside, he has natural passing instincts, and he can bring the ball up court better than TA, or House.
I dont see any reason he cant take Cassells minutes, and some of houses min when not playing well, and backup RA at the 2 while TA is out, we should be able to play him 10 to 15 for a while and see what he can do.
I also like the idea of playing him with Rondo, I think they could make a solid backcourt someday.
