Lol you're funny. Margarito is a bum, Floyd would pot shot that chump all night. He couldn't even beat Shane and he couldn't beat Cotto without the plaster.
First look at Cotto's face after he could Margarito.
Then look at Shane's face after he fought Margarito.
Then look at Shane's face after he fought Pacquiao.
I don't think he would have beat him as bad as Pacquiao did, but that would have been an easy night for Floyd.
