Does Caind beat Werdum and then, after surgery, does he win or lose to Miocic? Or does he lose to Werdum but somehow eventually meet and beat Miocic anyway? Personally, I think he eventually fights, but loses, to both.
At the same time, he loses. ;-) Werdum has Cain's number, simple. Better striker and grappler. Miocic would school Cain. Better wrestler (he touches you and you go down) and better power in his punching.
