A bad matchup for the general boxing public. Two counter-punchers will not make for an exciting fight!
Guzman is a counterpuncher. He is very hard to hit clean, and he has great handspeed and movement. Marquez is too old to be chasing him around and would get pot shotted all night and have rounds stolen from him since Guzman throws a lot of flashy pitty pat shots.
You are right I hate that ****, but I still would love to see it. And thats why I never cared to much for Jones vs Hokins II
Marquez is naturally smaller... It would be close, but Guzman just has a tough style to look good against while he ends up looking good. It would be competitive but his flashyness and skill would win the judges.
