Like I've said many times, he would be a Draymond Green type of player and I've been criticized for saying it. Maybe in todays' game he would find a jumpshot eventually but probably not...he would be too small to play PF/C and not even scoring ability to be a true SF wing. Like you said, the only reason he dominated on the defensive end bc their was a lack of talent in the NBA, only 8 teams and he faced guys less athletic and much shorter. He played with 5-6 HOFrs. He isn't a top 50 player ever...probably not a top 100-150 player honestly.
He got dominated when he faced Wilt.
