130 lbs. 12 rounds.

Chacon wins this one by late ko..like Chavez-Mayweather 2 although closer...

Mayweather has the ability to win this but I think that Chacon was tougher, and after the 9th round, would do more to ensure a close split decision verdict.

I think Mayweather outboxes from the outside to ud or tko a game but outclassed Chacon. Chacon isn't Chavez and couldnt cope with the speed and reach of Mayweather

Tend to agree. Mayweather could always get caught but I can see Mayweather pot-shotting Chacon for 12 rounds from the outside
