I'd pick Guts as well. That movement, plus the jab should make for a win. I don't think Mancini has more power than Rodolfo, who couldn't stop Guts in two tries. I also don't think he'd be able to pressure Suzuki enough to win the rounds. This fight might well be hard to score due to the styles, but I think Guts' class as a better fighter makes the difference. Also, I don't think a shut out of Ramirez is indicative of the level of fighter Mancini was. Ramirez was in a transitional phase, and wasn't yet the pressure fighter he'd be at his best. At that point, he was a counter-puncher, who had a good night against Arguello (who, he, in turn, had a style advantage over). Mancini was stronger, and so didn't let Ramirez set.
