Had most of these guys remained healthy, they could have changed the history and the landscape of the league. We have classic ballers like Maurice Stokes and Bill Walton, HOFers like Larry Bird and Pistol Pete, and even a couple guys in recent memory in Brandon Roy and Agent Zero. Let the
"what if" debates begin!
