right now i don't know....i'll wait till Cotto vs. Margarito....not that Margarita is/was as good as Mayorga back then...but it will show how Cotto deal with someone that is much, much bigger than him...
Of Course Mayorga has a chance. He's naturally bigger than Cotto and has a better chin. Power is pretty close to equal. Very good matchup! 147lb was Mayorga's best weight (he was out of his element at 160lb when he fought Tito), wasn't damaged as yet as was supremely confident. I like Mayo by decision.
This is a hard fight for Cotto. If he can get to Mayo's body he may break him down late. I say the first 5 rounds are dangerous for Cotto. Hard to say. A prime Mayo was tough as hell.
