Tito had a bigger punch than Cotto, but he had something else over Cotto which would have served him well against the relentless Margarito..... stamina. Tito's stamina was exceptional. His cardiovascular recovery time between rounds was one of the best. He could go on and on and on and on. And while Margo's chin is truly awesome, at some point Tito's huge left hooks would take their toll.
