Well, I think Aaron was one of those guys with the talent to be an all-star, maybe not quite at that level but good enough to put in 15-20, plus 6 boards and 5 assists.
He had a decent outisde shot, and a strong wide body. He was quick enough to get open, but maybe didn't have enough moves to be a primary scorer. The only thing that kept him back, IMO was him. He'd defer to Iverson and whoever else, instead of taking matters into his own hands.
He was well coached throughout his career, plays defense very well and has good hands. But he wasn't a consistent scorer, and he could have been. Some guys just can't play that well that you'd want them taking 10-15 shots per night, but if I was his coach I would have demanded that from him. Of course, Brown never wanted that, but he's obsessed with defense.
