Against Acosta, Rios reminded me of Rocky Marciano the way he never stopped coming , and the sudden, devastating knockdowns from out of nowhere. Acosta cracked Rios plenty of times , and Brandon shook it off. Having to deal with a swollen painful hand as well as a scrappy world class Acosta makes Rios's accomplishment even more impressive. Soon, we could see Rios against Marquez or Kastidids.Some hot fights to look forward to.
