I don't think so. Not because Marquez is the perfect gentlemen, but certainly he has to realize he didn't do much to do deserve this fight, or this pay day. After losing to mayweather so badly, if Pac doesn't KO him it's almost considered as a dissapointment. So, he's bound to appreciate this fight, and the $, and thus he's going to be humble. The first two fights were pretty close, and I can understand how he'd be a little upset, but he was pretty childish about those.
Jmm will most likely say Pac is stronger then the last time he fought him that will be the truth though.
