it's been no secret that both men plan to knock each other out in their upcoming fight and i think it's a great selling point to attract paying customers who've seen pretty much the same thing over and over again.
however, marquez plans to go all out and looks to knock out pacquiao which realistically speaking is almost an impossible task considering pacquiao's iron chin. pacquiao early in his boxing career did suffer two ko losses to lesser fighters via crushing body shots which marquez is not known for. since then, pacquiao has proven himself against notorious body punchers like hatton and margarito which he's defeated in convincing fashion.
bottom line is pacquiao looks good against fighters that come forward, and marquez being aggressive might just lead to his early demise. if he does stick to his usual counter punching and able finish the whole 12 rounds, pacquiao's offensive minded style might just be the winning point for the judges to him him the nod once again.
in any case, the odds in pacquiao's favor are well justified and marquez has a hell of fight in front of him when he faces the mexicutioner.
