Scott Smith is the master of the surprise punch. He's getting dominated for 2 and a half rounds and still gets the KO. That just crazy! I would never have expected that. Holy shit...
And although he won, I wasn't too impressed with his performance. It's time for him to step up his TDD and groundgame already. If Cung had just had a bit more of a killer instinct he could have finished Smith lots of times during the fight and most likely in the first round.
