TitoFan - Cotto fought Martinez at 159 and Geale at 157. If so, why not fight GGG at 160, or even 159, like Martinez. The only reason not to do so is to avoid him. With Canelo, as far as I'm aware, he's never fought above 155. So, he would be moving up in weight 5 pounds to face GGG. That's a better excuse than Cotto's.
