There is no way he will improve in his 30's like Hopkins did. He is just not that type of fighter, imo. He may break the mould but I don't think he is a type of fighter who necessarily improves greatly with age (beyond 30's).
Well, unfortunately his manager relies too much on Mike Marley and Marley screwed up in the Miranda fight. If the next isnt a big fight Marley should be sacked.
