Very close one but I'll say Young. His talent for his age is just light years ahead then everyone else. He is just a pure hitter with pure power and will be an MVP one day while Upton will "just" be an All Star. Upton is supposed to have 5 tools but he was pretty bad on the field in the few games he played with the D-Rays. He may have been overhyped as an all around player.
