Overeem has great wrestling? Cain would just take him down and pound the shit out of him.
Overeem's stamina is horrible so even if Cain decides to stand with him if Overeem doesn't keep Cain at the end of his jab & end it in a few minutes, Overeem will end up on the ground either getting pummeled or hitting the ground out cold.
