Taking underdog Marlon here. I think he catches Merab in a sub in a wild scramble.
.Merab is a great wrestler, but zero submission threat
highly doubting that Matt Serra student has ZERO....I MEAN ZERO SUBMISSION THREAT
Probably Merab, as Moraes's gas tank gave me cause for concern the last time he faced a high pace wrestler (Cejudo). It's hard to imagine it being much better now that he's over two years older than he was in that fight.
