How many fights would have a different outcome had they been set for 15 rounds?

[Onix]

Margarito-Cotto.. Had they fought in a 15 round era, I guarantee it, Cotto ends up on his knees 10/10..

Leonard-Hearns 2.. I love the hitman but ray always puts it on him late and he would have lost again..

::SMH:: If that fight was a 15 round fight it still would have still been stopped in the 9th because of Margarito's eye, 12 or 15 rounds dont matter in that case.
