1. Michael Jordan
There is still only one Michael Jordan. He's 50 now, a Hall of Famer, and thoughts of any further comebacks are (hopefully) just talk. But even as LeBron James threatens to encroach on his "best player ever" status, Jordan continues to stand alone as the only influencer who's ever truly mattered. Kids who weren't born until long after he played his last game continue to do anything they can to score his latest shoes. That's power.
