cain already knocked out nog...
Back on topic - Cain wins by ubereem gassing.
In Nog's last three fights, he knocked out Schaub, if he wasn't looking for the sub he'd have knocked out Mir, and he knocked down Herman to get the submission. Nog's boxing has crazily improved recently. I think he does well with Cain on the feet, along with Werdum, and on the ground both get the sub.
I can't decide Cain Vs Overeem yet. It depends on Reem's TDD and grappling really, but Cain has to watcg engaging that clinch.
