How do you see this explosive fight go? Does Rosario have enough firepower to trouble a sharpshooter like Tszyu?
Rosario takes this one - better boxer and had enough power to keep kostya at bay, possibly even stop him.
Rosario didn't fight at JR. Welter until late in his career and at that point he was pretty beatable. Tszyu was a career JR welter that was built more like a legit Welterweight. I think Rosario is thought of as the better fighter pound for pound but he would be fighting out of his natural weigh class against a guy that was no joke. At 140 I would be taking Tszyu only because Rosario was past his prime at that point.
Keeping Kostya at bay wouldn’t be advisable. That’s where he did his best work. I’d pick Tszyu to stop Rosario, who was better at 135, but still not as good or consistent as Tszyu at 140.
Rosario was on his last legs at 140. I was surprised that he beat Loreto Garza, who was a better fighter than he showed against Rosario. But he came in cold and got caught.... Kostya is too smart to do something stupid like that and more than smart enough to keep his distance, land his own right hand. He would stop Rosario in maybe 4 or 5.
