its safer to say that jmm has every characteristics of those guys
but unfortunately only a bit or a part of, he doesnt stand out of any
not as big as the heart of those three
not as physically gifted as pac (if theres one thing missing with pac, jmm has it)
not as clever as barrera (hes close, but MAB is pretty much as a slugger too like pac and EM)
not as proud as morales (he showed heart against pac, but EM showed heart his whole career)
i think the reason why hes not the one of the 'mainstream' guys is because he's best known as a counterpuncher and we all know counterpunching depends on the opponents offense thats why he is in a boring fight most of the time. if hes against a boring guy then he himself will be more boring to watch. he was best remembered in the pac fight because he stepped up a notch by showing the world that boxing is not just purely punching and strength. he showed the world that the skilled is better than the strong.... he may have the best defense because again, hes a couterpuncher.. MAB, pac and EM had shown they can counter punches but unlike marquez they dont do it all the time.
that being said... whos the one-dimensional fighter?
