To be honest, I don't think much of him; I don't remember any fighter that did improve significantly under his guidance and most of the advices he gives in the corner are most of the time pointless and turn around the lines of: "COME ON", "DO SOMETHING", "GO FIGHT". I remember Donaire vs Rigondaux, I've never seen someone as clueless as him in order to try to make a difference.

NAcho though, that's all another kind of a beast, one of the finest out there without the shadow of a doubt.
