IMO Cotto and Marquez are the most deserving outside of Mayweather, Bradley hasn't really done too much to get the shot and Peterson much less, IMO Cotto would surprise a lot of people on here in a rematch, he's in a good place mentally, actually has a corner now (and a damn good one at that) and he's boxing more now than he has in a long time, he hasn't really taken punishment since the Pacquiao fight and the fight would be at 154, hell even Rafael was picking Cotto as the best choice of the 4 (only barring Marquez cause although he was robbed in all 3 what's the point anymore?)
