How much of a factor was Cotto's broken nose?

[MaFu MoFo]

A factor, as Cotto ran out of gas. Cotto was too tired to "hit, land and run". Margarito slowly hunt him down. But if Cotto had better stamina, Margarito would had not landed as many punches as he did after the 6th round. It's not only the breating difficulty, but the loss of hemoglobulin. (which carries OXIGEN to the all the organ tissues.) He was weaken faster than expected. Add to it, Cotto's lack of body work on Tony... a fresh Margarito and a weaken Cotto for the last 2 rounds. UPSET IN THE MAKING.

The nose certainly didn't help, but like Antonio said it was caused by a Margarito punch. Just like When Marco Antonio Barrera caught Morales with a nice uppercut in their third fight and broke his big ass beak. It was a distraction and didn't help his breathing, but it happened because the opponent made it happen.

I think it was a big factor, but a legit wiwn non the less

It could have impacted his stamina but those body shots he took had something to do with that as well.
