Explosive fight for sure! I think it plays it with Rosario badly hurting, or dropping Arguello early, then Arguello rallying back to take over, and stop Rosario late. That's the only way I see it playing out actually.
That elbows out posture is all wrong for this opponent. Arguello was a brutal body puncher and the punch is available on a silver platter. tko6 and like mentioned earlier, once hurt, Rosario goes into his Frank Bruno type survival skills and they won't work against a finisher like Alexis Arguello.
Don't think Rosario's chin is good enough to survive Arguello. His power keeps him in the hunt and he'd have his moments, but he'd get broken down by his relentless opponent. Arguello by late TKO.
I don't think Rosario will have that much early success at all tbh. I see it a bit like the Margo v Cotto fight where Rosario will assume the role of boxer because he will feel he has better hands peed and movement but I think come fight night Arguello will be able to match every facet of Rosario's game. I reckon we might see Rosario nick the first 2 rounds, the next 2 be shared quite evenly and then from then on Arguello will be on top wearing Rosario down before ultimately stopping him.
His fight with Jose Luis Ramirez he turned his back in the 4th round rd and maybe that is what some are talking about. Ramirez was tough as hell and hit hard but I don't think he dropped him. As good as Arguello was and as hard as he hit I think Rosario hit harder at that weight and IMO their aren't many who could hit like Rosario at 135/140. As great as he was at 135 Chavez was better and Chapo went 11 brutal rounds with him. It depends on which Chapo shows up the Bramble or the Ramirez fighter.
