Even though Charles Barkely was generously listed at 6'8 he was more like 6'5 and killed rebounds. I dont know if Oscar Robertson ever led the league but he was up there as well for not being the tallest guy in the world.
I do beleive "the round mound of rebounds" was the chortest player to lead the league in boards. Chuck was nasty at bball. The sixers need some with the intensity of a chuck barkley.
