Wear and tear

martinez said his knee was affecting him even back in the chavez fight in an interview with thaboxingvoice

here is the thing with Martinez is he never learned how to fight he was a great athelete fought with his hands down and relied on his feet and reflexes but with his injuries all of that goes out of the window Nazim Richarson said it best it also applies to Martinez in this case some wise words from the best boxing minds around period starts at 05:30

Roach doesn't want to think that he failed as a coach in the Chavez-Martinez fight, so he's trying to salvage something by saying Chavez is responsible for Martinez' downfall.

there was no wear and tear in the that fight it was Martinez on auto pilot for 11 rounds probably the easiest fight for him after Williams II
