Grant Hill has arguably one of the greatest "what if" NBA stories we've ever seen as it relates to catching the injury bug and having a derailed career. Hill may still be playing today, but he's a shell of what he was before he got those nagging ankle injuries that left him playing 47 games in his first four seasons with the Magic. He was a budding superstar going into the move to Orlando but the time off the court forever changed the franchise and Hill's legacy. He went from a triple-double machine/superstar with endorsements up to his ears to a solid role player.
