Bolt is in a league of his own for sure--but honestly I don't care too much on how he carries himself. Hes a little too cocky for me---but thats my opinion. I like how phelps carries himself---and lets his actions do the talking. Phelps is in a league of his own---no real comparison. If you wanted to get more specific...have bolt run 4x400 relay, 400m, 800m and the 100 and 200. That still wouldn't be an equal comparison to what Phelps has went thru!! Phelps has accomplished something that NO ONE in the olympics has ever done before. Go TEAM USA!!
