The young Akeem. DoD is on the money. Barkley (simply because of his awesome takedown of Shaq... wow!) Calvin... toughest little guy in the league in his day. Max. Moses. (in that order, imo. I'm sure I forgot someone, but I'm glad I got to see these guys play when they were bringin' it)
If you saw the 86 WCF versus the lakers, you would know it was Dream. The guy didn't care who was guarding or how many people was guarding him, he was going to dunk the ball and he did. He was consistently double teamed by Kareem and another Laker and he still scored in the 30's. Moses was a close second.
Got to be Mad Max. If you go postal into the stands after an imaginary adversary, you got to be the most aggro. .
How about Rudy T as a player. Calvin Murphy, Hakeem, Mad Max, OT, M.Malone All great choices. My favorite Scotty Brooks.
I'd have to go with David Wood and Scotty Brooks. Those guys were all over the place, giving up their bodies for the team. Actually, I guess they would be more "scrappy" than aggressive.
