Chavez boxed well, but seems to not have the output he needs to have to win. I actually think he could stand in there with most 168ers - although that of course wont be easy. But he will get better speed-wise as he comes up. I had Martinez winning 8-4, but most rounds were close because Sergio hit the gloves a lot. All in all a good fight and both men did well.
Chavez got schooled. as far as weight: he will have to move up as he gets older. He does not have that many fights left at MW
Martinez on a different level....chavez jr is tough though needs to improve his activity rate when fighting by increasing his handspeed and footwork, and has to use more jabs and combinations.
I was a bit generous. But there were rounds where Martinez throwed much more, but hit almost entirely gloves.
