126 pounds-12 rounds.

at 126 I'll take Chacon.

If Chacon didn't bleed too bad, I think he wins a UD, something close like 7-5. A big iff, but he was the better fighter at 126 IMO (and I was a big JMM fan)

Marquez decision

At 126 Bobby can beat him.

It'd be a 50/50 fight though and Marquez coming out with a narrow decision wouldn't be impossible to imagine or nothing.

As they went up Marquez improved whereas Bobby deteriorated so at a higher weight class Marquez would have the edge.

At 126 this would be a tremendous battle. Marquez was primarily a counter puncher, but an aggressive one that would get into firefights with opponents if they were bringing the heat. Chacon definitely would be bringing the heat.

Chacon by decision in a great battle with Marquez.
