I'd be rooting for Cotto, of course. But I'm also a big fan of JMM and have always respected his great boxing abilities. To me it depends on the weight. If Cotto were willing to make 147, it would be a very interesting and action-packed fight. Any lower than that, Cotto would be weight-drained and it would play right into JMM's hands. Any higher (than 147)... and JMM has not shown the ability to dominate at the higher weights. Cotto would win. At 147, it would be a toss-up. The Cotto that gave Margarito a boxing lesson would present all sorts of problems to JMM. But who knows?
