His logic falls apart at the fact that I'd walk on Cena's side all day because he's a guy that wouldn't know what to do with being punched square in his face, his meathead look intimidates the average cat sure but as a whole guys like him aren't used to getting hit.
Say what you want about KO but he's a cat that looks like a dude that doesn't mind/ain't afraid to get hit because it's likely actually happened and he's had to deal with it one way or another.
