Well, you look at guys who have athleticism and they can be great or they can be good or they can be duds, dependent upon a few things. Reaction times slow when one gets older - people eventually figure out freakish fighters and take away the best thing that fighter does. Also, the aura of invincibility goes away once someone knocks them off the mountain and suddenly we're not talking about the same guy.

Examples... Roy Jones, Jr. was freakishly athletic (steroids talk aside, he was that way in the Olympics). His reaction time has slowed and once Tarver KO'd him, the aura was gone. He no longer believed he was who people thought he once was, and that was one of his greatest attributes.

Berto is a great athlete. He is a knucklehead in terms of using that to his advantage, so his athleticism got him only so far, until he fought guys that can really fight.

Hopkins is not the most athletic guy, but he is an example of a guy who uses what gifts he has to his advantage. He is always in top condition and he has better stamina than most of his opponents. He is also very smart in the ring and adapts to the other guy's best 'stuff' - he takes away opponents' best athletic attributes.

I'd say Seth Mitchell is athletic... but is he a boxer? Not really - he doesn't have 'it' - whatever 'it' is.
