JMMs different tactic in the 4th fight..

[ruthless rocco]

Marquez defo sacrificed spped for power and its a gamble that almost backfired. Just before the KO he was behind on the cards, marked up cut and looking gassed. Pac saw blood rushed in and Marquez was able to time him. Had Pac had a better boxing brain/trainer he would have eased off and continue to dominate with in and out boxing.

Here's a video of what he focused on during his training, and that is Pacquiao's typical jab jab followed by a straight left.

yup... That looks about right. Good post.
