bottom line he will win...marquez is a GRET fighter...floyd has fought great fighters before and has never lost...this will be a big win for floyd who is not a huge 147 lb guy...marquez is by far the best at 135...so no excuses when floyd beats him...then he will beat pac and whoever is #1 at ww at the time and retire
At this stage of his career, JMM would not pose a threat to Mayweather. JMM had a hard time against Diaz, a fighter Mayweather would easily out box, or, even KO.
