Average their stats together and its a 65% chance of a KO in under 5 rounds with a 24% chance they go the full 12 rounds.
Acosta won't go to stand and fight, he will be moving all the night. It could be under 9.5 if Acosta hurts Rios. I can't see Rios Knocking out Acosta. My prediction: it will a full distance fight wiith Acosta winning the decision.
