How could mayweather fight manny instead of Ortiz, when manny agreed to Marquez before the Mosley fight?

"thug", you are on a roll today! this is very true. turns out arum had marquez in mind all the time. some publications have found exact quotes from arum. and as far as turning down money, well, manny did the same thing or does march 13, 2010 not mean anything to some?
