I would say that right now Manny has more bartering power than Floyd Mayweather and if this fight does take place he needs to stick to insisting it takes place at 140 lbs.

At 147 I think Manny gives up too much size and nullifies his chances but if the fight is made at 140 lbs, completely fair imo as Floyd can easily make that, then we are in for one hell of a fight.

A win for Floyd would mean more for his legacy if he beat Manny at 140 as well I think so I really hope the 140 lbs weight limit is where the fight occurs.

Also presuming Floyd beats Marquez then if this happens around Christmas it really would be the biggest fight in most of our lifetimes imo.

The winner (even if its Floyd) has a stake at being one of the top 3 fighters ever and maybe even challenging for number 1.

If Manny wins he would have run through 10 weight classes and beaten literally everyone great who was available to fight in his generation.

If Floyd wins he would also have beaten all the greats of his generation up to light welter, and I really don't hold it against him too much if he skips on Williams and Mosely as Floyd is a small guy too who fought well above his weight limits.

If Floyd retired undefeated with wins over Corales, Castillo, De La Hoya, Hatton, Marquez and Pacqauio that's a serious legacy right there and if Manny rose from minimun weight to going 8-1-1 against Marquez, Barrera, Morales, De La Hoya, Hatton and Mayweather, for me that would be the best resume of all time.
