Umm, who said all that?! The only thing I, and others, said was that from a money perspective (and he IS Money Mayweather) fighting Khan is the logical thing to do, and something he's been wanting to do for a couple years. NOBODY said Khan had a chance of winning anything or was the best possible opponent, I don't know where you're getting all that.
And the fact is, Rios was, once again, made to order for Paq. He's the same type of fighter Manny's had the most success with over the years and was a logical opponent to put him back in contention. And there's nothing really wrong with that coming off a loss, but call a spade a spade, it is what it is.
Martinez, at least a couple years ago, said he would be willing to drop weight for Floyd only, not Manny, so once again, I don't know where all this is coming from.
Should Floyd be forced into some match with Sergio? IMO, no! Regardless of a catchweight or not, Martinez is still a bigger framed man, and I don't feel it's necessary for his legacy, because people like you have their minds made up about Floyd and his place in history anyway, that fight won't make a difference, just like the Alvarez fight made no difference.
But do I think Floyd would beat Sergio? Absolutely! Not saying it would be cakewalk of any kind, but I do think he'd do just enough to win. He just shouldn't have to do that to prove anything, there's nothing left to prove. At least there shouldn't be to any fan or media personality with a rational mind...
