Cervantes via suprisingly clear UD. His jab, range and footwork would be hell for Chavez @ this weight.
I'm not sure if I agree but I think it'd be close. Cervantes is one of the most underrated HOFmers IMO. You rarely here about him, but he was one helluva fighter. Just watch his beat down of Dejesus. He handled Dejesus with ease, and Esteban was of course an excellent fighter in his own right.
