Caio is a gassy fighter, he was able to bully his last opponent with grappling because of his size, but Armen is bigger and more taxing standup wise, his body kicks will mass up Caio's gas tank.
This is the fight where he fought another kick boxer of lower skill and he was gassed by third round, i time stamped it.
Armen is better than that guy and he's going to give him a better pace and better defense, the fight is 2019 but i doubt his gas has improved, he loses third rounds often, he lost it in the jeffries fight, he lost it in that fight up there. This is going to be a very close fight, Caio has weak sub offense, and he loses top ctrl often too. I have armen decision for 500+ i think he edges Caio, wins the third and 2nd round by a close hair. I think the 2nd round will be the determine factor.
