dude I am Korean and it's too early honestly. He does need to go to the Military like Zombie (cause there's no way to get a gold medal in the Asian games or atleast bronze in the olympics for a MMA fighter as of yet). But he needs atleast 2 BIG fights (Top wrestler and a striker for the division)and then one contender fight.
I just hope he fights often cause as I said, he needs to go to the military and that's going to be a huge detriment for a MMA fighter...

Edit
But I do think he's power is underestimated, he does have almost 80% knockout rate.
