The brightest stars burn the fastest

[Kolumbo]

Bo Jackson - easy one to answer. No one burned brighter in multiple sports in such a short time - and then it was over!

Bo Jackson is my answer to various sports queries. He could have been a Hall of Famer in either football or baseball if not for his injury. Not sure if this particular category matches his situation but I consider him the greatest athlete of all time. Quality over Quantity. He may have even become 2nd only to Michael Jordan, if not first, in terms of marketing success if he was able to play out his entire career(s). It's not like he was a bust, just one lousy tackle ruined it all for us.
