This or at least the fights that he precives won't. Take Cotto for example no this would not be a compitive fight but Cotto is a very popular boxer. He probbly could make a lot of money for an easy night's work.
Margarito: Banned for Illegal Substances Cotto: Damaged Goods and his team passed on a Mayweather showdown at 140 after the Gatti fight. Mosley: He ran from a Mayweather showdown after Mayweather was eying a fight with him before his fight with De La Hoya. Pacquiao: About to pass on $40 Million because of voodoo. Also, 3 out of the 4 listed are Bob Arum fighters.
Mayweather will fight and beat pac man and my fav fighter Mosley. Id like to see him beat Pac, because he should. But id like to see Mosley beat him but I think Mayweather will show his guts for once in a great fight against Shane.
I will NEVER understand why people think Margarito posed even a mild threat to Mayweather. Margarito is, I repeat, a SLOW PLODDER who is the walking, breathing, embodiment of the word "predictable". He does nothing well aside from taking punches and moving forward. Floyd would have made it look easier than Baldomir. Edit: That said, we'll likely never see the fight since Margarito is a known cheater, currently serving a year-long suspension for loading his gloves illegally.
