personally i think marquez has just as much chance, both awesome fights, but it seems a lot of people are looking at marquez as merely a way of setting up the pac fight, im not convinced it will be quite that simple....it seems to me marquez is floyd's most acclompished opponent to date, not including size of course.
Seeing Pacman at or above 140 and the domination that he's shown,I'll say Pacman will give floyd fits for sure,because I cant think of anyone floyd has fought,with the prolific offense that Pacman possesses!!Marquez on the other hand is a very technical fighter,counter puncher and is more close to the type of fighters floyd dominates!!!
