I dont think this fight wouldve ever happened cause Valero handpicks easy fights. Valero ducked Humberto Soto many times. Soto can KO both Valero and Rios, back to back. JMM has also ducked Soto since 2007, and choose to fight Soto's "leftover"-Rocky Juarez, juat like MAB also did. JMM is too scared to try to unify his 135lbs belt with Soto's other 135lbs belt. In an interview, the ESPN crew asked JMM about fighting Soto, and JMM changed the subject. Pac has ducked Soto since 2006, and after Soto KO'd his brother Bobby on the Cotto-Judah undercard, Soto stood at the ropes and challenged Pac to a next fight, to see if Pac would avenged his Brother's KO loss. Pac chickened-out. Last year, MAB was given a shot at his 4th world title dream shot, the WBC Lighwteight title, but turned it down, cause he was scared to fight Soto. the same went for EM, he too turned down a shot at Soto's title. That WBC title that both MAB and EM turned down, was vacant title won by Soto, cause the then champion, Edwin Valero was to scared to defend it against Soto. Just cause Rios has said he'll fight Soto now, and Soto has other plans, doesnt mean anything. rios showed how vulberable he is against a B-level boxer-puncher with mediocre power, Acosta. Soto would KO Rios easily.
