Help!!! I'm Starting To Think Margarito Has A Shot!

I was of the belief that Pacquiao was too fast for Margarito and he would just move in and out while tagging him at will, but I can't keep acting as if Margarito will respect Pacquiao's power and Manny is some sort of defensive genius. Margarito won't just stand in front of Pacquiao letting himself get picked apart and giving Manny a rest period. He's going to be walking Pac down nonstop and throwing 4,5,6+ punch combinations even when he's out of range. Mosley was smart and strong enough to hold Margarito every time he was in range to land. And after he held, he'd walk Margarito backwards to tire him out. Can Pacquiao do this constantly? If not, how is he going to keep Margarito at bay? Pacquiao doesn't seem to have the lateral footwork that it takes to keep Margarito off balance and on the outside. Nor does he have an exceptional inside game where he can block punches if he does get inside. He can throw tons of punches like Williams, but Margarito will only wait for so long before he says 'A la verga guey' and forces his way inside. Margarito is 5'11'' and his main punches are the straight right hand and left uppercut, they will work well against a shorter southpaw. If Margarito can get to Pacquiao's body early, it'll get very interesting down the stretch. I still think Pacquiao will win because Roach is a master at game planning and if he has Pacquiao going to the body early, all of the above will be annulled, but if not this will be Pacquiao's toughest fight since JMM II.
