This week at UFC 321: Aspinall vs. Gane, Marley is backing Azat Maksum (-395) in his flyweight bout against Mitch Raposo (+310). "Give me Maksum here. Raposo is going to need to land takedowns and grind out control time, but I don't even think he is the better wrestler in this matchup. I don't know if Maksum dominates, but I do give him the edge anywhere this fight goes, and I'll take him to win 30-27."
