Draw ... My gut tells me to go with Margartio UD and then my head pick Quintana by UD so i'm going down the middle draw.
but you have to think Margarito is a slow starter .... Quintana has great movement with his upper body and head ... its a toss up and I for one would love to see it.
Don't forget about Quintana body punching ... he can punch effective to the body as well ... this is an equally matched fight on paper.
you have to remember cotto's head shots didn't really have much affect on quintana, it was only when cotto started going to the body when quintana got beat up, margarito isn't a great body puncher.
I would say that Margarito is not as skilled but better is a far cry. Margarito has a good chin and is as flawed as Cotto is... I think that Margarito given the chance can beat Cotto.
