valero has looked sensational against opponents of unknown quality. guzman who beat imo a better, harder hitting fighter in sotto, would win this easy. i'm not even a guzman fan, but the wide punching valero will be given a boxing lesson.
Valero is fast. Power = Force X Velocity. Valero is only 130 pounds so obviously he has a lot of speed if he can produce such power. Valero only looks slow because he telegraphs his punches when he's going for the kill. If he just boxes normally and doesn't overcommit on his punches, you can easily see how fast he is. Watch the fight with him and nobuhito honmo, after the 1st round he starts throwing wicked fast combinations. Guzman got hit with more than 100 punches against a slower soto. Valero would come in with more aggression and a lot more power. I doubt guzman can just shrug off valero's power like he did to soto.
