Well Floyd had to come DOWN in weight which he apparently had great trouble doing, he's older, and in his most recent fights with guys who can counter he has lasted the distance AND had trouble a time or two. I think this fight will more than likely resemble the Jose Luis Castillo fights, either JMM does a number on Floyd or gets a number done on him...I just think that JMM will make it very hard on Mayweather because JMM may be the only guy that is in his relative prime and can adjust in the ring as good as he can.
