That left hook would be the decider...but it would probably the the most adrenaline filled day of my life (next to cotto-margarito) so the biggest winner would be everyone watching the caios.
I think Cotto is slightly underrated,and Tito slightly overrated,but i see this as an action packed fight. I think they would both drop each other early and with the fight being even going into the 7th Tito puts the finishing touches on him in a thriller.
