"When" Floyd Mayweather loses to Marquez,

This will be a great fight but i see Mayweather dominating and winning a majority decision

I think a loss would do Floyd Mayweather the world of good but Marquez hasnt got much of a chance, Floyds bigger, faster, stronger, hits harder and has better movement and defence

Will it make him a better fighter? It might improve his legacy, by not being afraid to lose anymore since his "oh" is gone. Floyd might open himself up to a fight with Mosley, Cotto, a rematch with JMM. Floyd Mayweather losing to J.M. Marquez might improve his claim to A.T.G. status if he wins a rematch/ trilogy with Marquez, fights Mosley and Cotto and of course, Manny Pacquiao Bump this shit when I'm right, bitch he only came out of retirement for jmm and pac thats it.

I think so, People are so desperate to see Mayweather lose...I think he might even be loved more after losing, Wouldnt be surprise.

JMM is going to get the shit beat out of him. Its going to be worse than the Gatti fight. Harlem shake to that, lol get the **** outta here JMM TKO Floyd 11th round

JMM is going to get the s.h.i.t. beat out of him. Its going to be worse than the Gatti fight.
