Just because Sean plays center doesn't mean he can't use his dribble to get to the right spot; I don't think Norm wants a one-move, back to basket center type in the middle. I think. I am not completely sure what he's trying to run some of the time.
I think DJ did try to look for his shot more than I would like. His aggressiveness was useful, though it would work better if he had Mason's skills (put the two of them together and you have a really good player). Sometimes he took up parts of the possession just looking to probe; I think it killed the flow a little. It was kind of like how Mase took up possessions dribbling for his shot when his teammates were all freshmen.
Note: don't take that as an indictment/ worry about Kennedy + Mase next year. They did not play like that against Boston College; if anything, I remember a lot of ill-advised, perhaps too quick shots. With another player who can get a shot up on the floor, maybe both will more quickly see when they have a chance to score and when they do not, and pass it up; Mason knew in 2008 that he was the only scoring option on a team that couldn't score. Other years, he's not been as hungry for his shot.
