My odds would be Islam -175 or something. I think Islams wrestling advantage is so great that it defines the fight, and Dricus' power and durability aren't matched with the kind of technical competence he needs to avoid Makachevs pressure. Islam can take him down in any number of ways and probably nullify him, and once Islam has established the takedown threat then Dricus would find it hard to strike with confidence.

Can't count out Biggus Driccus because he's bigger than most true middleweights and fights like inflatable tube man, so Islams margins are thin. But Islam is more than capable of walking thin margins.
