Memphis let's just simplify this for you....Hatton has always fought at 140 he tried to move up he didn't do very well, and he moved back to 140.

Oscar De la Hoya hasn't fought at 147 in just over 5 years and he barely makes 154 now'a'days

That being covered a De la Hoya-Hatton fight wouldn't happen at 140 where Hatton is because Oscar can't make that weight. The fight won't happen at 147 because Hatton doesn't do well there and Oscar can't make that weight. This just leaves us 154, this is where Ricky has never fought and if Ricky isn't comfortable vs a Luis Collazo at 147 then fighting an all-time great a weight class above that doesn't make much sense now does it?
