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.
Charles could fill the lane and run on the fast break for sure...but actually, when he was in Phoenix, we were very much a half court team. KJ would break down defenses with penetration or kicking the ball into Charles...He would then use his big butt, and very patiently back down his defender...He would do that long enough that either he would feel the defender lose his position or balance, and he would attack, or until a double team would come and then he would find Ainge or Marjerle up top for 3. Charles was a versatile scorer, but his ability to back down a legit sized PF, when he was just 6 ft 4 (generously) is really quite amazing.
