Mayweather may very well do a number on JMM, but JMM will never be out of the fight and may perhaps come from behind to win this. I think as smart and as tough as JMM is and with him coming UP in weight and Floyd going DOWN in weight, I wouldn't be surprised if JMM sparked Floyd out!

JMM may go down early and often, but he'll be around at the finish!

We could see a couple different outcomes of this fight, some mirroring the following (in bold are the ones I think are most likely):

Chavez-Taylor
Chavez-Mayweather
Chavez-Whittaker
Mayweather-Castillo I or II
Mayweather-Hatton
Mayweather-De la Hoya
Mayweather-Corrales
