This week at UFC 307: Pereira vs. Rountree Jr., we can tell you Marley is backing bantamweight Mario Bautista (-175) to defeat UFC Hall of Famer Jose Aldo (+145). "Aldo looked great in his return fight, but I think this is a much tougher matchup. A three-round striking match could be close, but I think the pace from Bautista will be too much and he can also mix in the wrestling as well. I'll take him to win 2-3 rounds," said Marley.
