I agree. If Cotto stays with his current training camp, especially his current trainer, then Cotto's days as a top tier contender are basically over. In the situation like this, he needs fresh eyes and a fresh perspective along with a ton of experience to help him get back on track, and Santiago is not that guy.
I would say Nazim but isnt Shane being trained by him? So I went with Stewart cos I think he would help Cotto with his D game
Let's watch Cotto's next fight first before blaming the trainer for the loss. Remember that he faced Pacquiao and I'm not sure if any other trainer could have given him the W.
