Beating floyd is a great accomplishment especially considering who has failed at doing it. If it is by ko i think he'd have a solid case. Beating castillo (on the slide maybe but not completely shot by any means) and floyd (if hatton did this at a higher weight it would be an even more impressive accomplishment and would get a lot of people to quit calling him overrated and, in extreme cases, a bum) in back to back fights by ko would be incredible. If it's by one sided decision (least probable outcome of this fight imo) he moves up the rankings but probably doesn't get #1 and if its by some close and possibliy shady decision, it probably won't do him much good aside from having a HUGE name on his record. Don't get me wrong if he beats floyd, by any means, it would be huge for him but if he does it by shady decision, he doesn't do himself any favors.
