Rosario. Marquez was great at lower weights. He's not really a Lightweight, he looks very small compared to guys like Katsidis and Diaz. He's having rough patches fighting these guys, he's able to dominate Lightweight because there hasn't been another world class fighter in the weightclass. He loses to Lightweights along the lines of Roasario, Duran, Mosley too.
This comes down to two things for me -- Rosario's punching power and Marquez's susceptibility at this weight. Rosario wasn't just a lumbering caveman, he had the technique, timing, and speed to land on JMM. There's absolutely no question about that. I can see a very competitive, back and fourth war for the opening few rounds, but Marquez is sooner or later going to get hit hard and he'll do well to recover. He may get up and fight on, but it would only be a matter of time before Rosario found the mark again, in my opinion. Rosario earns himself a stoppage before the 9th. He was a ridiculous hitter at 135lbs.
Rosario was a hell of a boxer-puncher, and could hit like a mule. He also was as tough as nails. Chavez beat him, but afterwards he gave Rosario alot of props. JMM would do well for a few rounds, but then Rosario would hurt him badly and knock him out. Rosario was one bad fighter!
Marques knocks his ***** ass out. Rosarioe always came up short in big fights and was nothing more than another druggie coke head from that one island (see Camachoe, Gomez, Benitez and from what I hear Cottoe for prime examples).
Yeah, I'm gonna agree, especially if we're talking about the earlier Rosario. He was like a poor man's Wilfredo Gomez/Ricardo Lopez mixture (I'll explain if asked, trust me), with more power than either. This just doesn't bode well for Marquez.
Marquez took a lot of punishment from Juan Diaz and Michael Katsidis. Rosario was in a different class than those two, hit substantially harder, and would prove to be way too much for a shopworn lightweight Marquez, who I really don't rate highly at all.
I'd go same as above except JMM by a point or two. Great question,Rosario is undervalued in my opinion.
After about 7 competitive rounds, Chapo drops Dinamita hard (after having dropped him a couple times before), and stops him. Rosario hit way too hard.
Rosario was a very good technician like JMM. Juan is better with the combinations, but Rosario had scary power in both hands. Both are/were excellent counterpunchers.
