Balkman is pretty good player, and he reminds dme of Ron Artest. However, he does seem a bit weak from what I saw. His forearms looked pretty small, yes I know you can't judge strength from his forearms, but they looked pretty pedestrian to me.
As for the JPR, dude serioulsy STFU. This post is about Balkman's dunk, and nothing else, so leave the Bulls out of this discussion.
