Congratulations Margarito on a great fight but Posters are getting carried away. Margo does not ever at 147 beat a prime Duran.
Duran would show Cotto how best to fight Margarito -- catch him coming in, sidestep, slip, clinch, work off the clinch. Duran would not be standing in front of him all night but he wouldn't be on his bicycle. He'd be making Margarito reach, and taking advantage of it, and work on the inside a bunch with his shorter arms and advantage in handspeed.
