Think about it. If Margo decided not to risk getting mugged, he could have just covered up and we will end up watching Pac-Clottey again. But Margo lived up to his mexican warrior mentality and hunted Pac down the entire fight like he did to Cotto, willingly taking many punches just to try to land one of his own. If Pac's stamina were less than great, he would have slowed down mid rounds and Margo will start to take over and land punches. Cheers!
AM's mistake was not using his height and reach advantage. He should have used his jab more often to keep distance between him and Pac. Attacking Pac is not the way to go about it. Past opponents of Pac tried and failed using this method.
I think I saw AM tried to utilize his jabs many times in the fight but he got countered a lot right after throwing.
Jab and move, jab and move. AM didn't do it. He jabbed and stayed there. That and the fact that Margo's defense is atrocious, like always.
