Is not the shot attempts, although it is extremly disturbing that he is taking more shots than KG/PP/Allen on a per-min basis, but the lack of rebounding. What' up with that? If Perk is not giving you defense and rebounding, then What is he doing? and it gets worse once you bring his backup - Sheed.
I agree with some of the posts out there, less Sheed and more Baby and possibly SWilliams should be a good thing.
Anyways, Perk needs to be, what he is, a defensive force and a solid rebounder. Anything else is gravy - but a distraction - if we keep force feeding.
