Is Freddie Roach overrated?

I think we can all agree, the second half of last year was a terrible on for Freddie Roach. Manny Pacquiao got schooled again by Marquez, Linares got knocked out and Khan lost to Peterson. What did it show us? Well despite Freddie training fighters for more then two decades, he still can't teach even the elite how to defend themselves. Manny Pacquaio is the first to spring to mind, His speed, power and combinations are up there with the best in the business, but once backed up he can't defend himself. He has one game plan, and thats to throw a mountain of punches at awkward angles. When Manny was struggling with Marquez, Freddie had no plan B. Infact in several cases, I notice Freddie gets extremely nervous come fight night and does not know what to do when the going gets tough. His fighters all seem to struggle to fight on the inside also. Amir Khan for example this year, when Peterson got him in the inside, Khan would hold and push. Which in some peoples minds cost him the fight. I think the man who deserves all the credit from training camp preparation for Roachs fighters is Alex Ariza. Where does the speed and power, that both Pacquiao and Khan possess come from? Certainly not Freddie standing there holding mitts and wearing a body bag, It's from Ariza's relentless training and track work. Khan left Ariza for how long? One fight. Why? Cause there is no strength and conditioning coach in the business like Alex Ariza. In my opinion Freddie Roach is extremely overrated.
