no one can really judge Valero's chin cause it's never really been tested, speed i'd say is dead even, and power goes to Valero, but overall boxing ability although no Mayweather goes to Soto, i see this fight beeing a tough one probably Valero winning the early rounds by smothering Soto and muscling him around, but Soto working the body and seeing how Valero tired a bit the only fight that he went up to the 10th, although he clearly still had the power, i'd think it'd be the first fight to go the distance, and maybe even a SD loss for Valero, really a pretty even fight though
