Eventually it does. As we've known for a bit, Rios has some give in him. And Corrales would be the hardest hitter he's faced. After a few rounds of taking those bombs, he'd cave by around the 9th round.
Agreed. Plus, Corrales' chin was more vulnerable to speed than power. I could see Rios hurting him several times, but I think Chico could weather it. Overall, Rios would just get hit too many times here. Corrales was by FAARRR a better offensive technician. Corrales TKO 9. Rios most likely still on his feet, but getting badly hurt and tee'd off on, and ref stops it. Probably a similar stoppage to what we saw in Gonzalez-Viloria.
