Anyone giving Floyd a shot at the UFC level of MMA having a shot of beating anyone needs to see a doctor.
Last time for the slow ones:
Boxing and MMA are different sports. Just like football and rugby are different sports. Sure - same general idea - run a funny shaped ball from one end of the field to the other while guys try to stop you by tackling you. In MMA and boxing, you try to get the other guy to quit, knock him out or beat him on points.
But that's about where it ends. Movement is different. Rings are different. Spacing is different. Hand placement, strategy, physical tools necessary to succeed, point scoring - all of it.
Floyd fought Conor a little different by walking into him and making him punch himself out - because Conor sucks at pacing himself in an MMA fight, let alone a boxing match. Conor caught one uppercut, but otherwise gassed out and got his face boxed off. Because he's not a boxer. And he clearly doesn't have any idea what he's doing.
Watch Floyd go into an octagon, get his ankle picked and get his face smashed in with elbows. Might survive a round if he's lucky. It'll be a fun freak show, fun to watch Floyd get murdered, but that's about the only appeal.
