Werdum's muay thai (especially the kicks) looked real sharp and when those big boys are throwing their bones around whatever can happen. Imagine Cain gets his rib broken in the first like Travis did. Not so easy to steam roll the next 4 rounds in a condition like that.
Werdum is a BJJ monster but still I think he subbing Cain is a bit far fetched, unless he knocks Cain senseless first. Either way it's dumb and ignorant to say someone would win a fight at this level "easily" lol.
