Its doubtful we'll get any more than what's there in the manual, although I'm sure friends of the game developers will probably know exactly what's what.
Charles Barkley and Hakeem Olajuwon for example were two of the greatest inside scorers ever but neither relied on backing a player down. .
That's true but I guess I remember him always running up and down the court in Phoenix's fast break offense, not backing people down. His great ball handling is what enabled him to score in such a variety of ways. He was so good he even played point forward quite often.
