If u fellas watch the Martinez vs Pavlik fight, you'd see Pavlik did a much better job of attempting to cut the ring off. He actually looked smart at times and took control of the fight until round 9 when Sergio bloodied him up.
There was nothing that Pavlik did that Chavez is not capable of doing. The problem is he needs to get his pops training him instead of that dead beat trainer Fred Roach. And yes, punching without having your feet set does take away from your power but those are the types of things your supposed to train for, so it feels more comfortable moving and punching. Chavez was poorly prepared for the fight, showed no knowledge of how to cut the ring off. At least Pavlik at times got his lead foot outside of Martinez's, Chavez i dont think at any point had his foot placed outside of Sergio's. He just chased Martinez, played right into his hands and was a sitting duck for Sergio's punches until the 11th round where he finally applied pressure in a more strategic way.
