Why is miguel cotto's jab so underrated???

its one of the best in the business, he needs to use it as much as possible.

I agree, His jab is very good. The problem is that he doesnt use it enough because he always wants to fight rather than box. To this day I still consider the fight with Mosley to be his best performence and that was because he used his jab perfectly and everything else came naturally. The reason he used his jab more is because he respected Shane's power, If Cotto laid back and used his jab more then he would be much better I think. When you have power like that you are going to knock people out sooner or later so I dont know why he doesnt box more.

He doesn't stick to it. Or that his opponets adapt to it and he has no answers.

It's underutilized. I think most people acknowledge the fact that he has one o the best jabs in the sport. He needs to use it more effectively.
