Event: UFC 146 - May 2012 Roy Nelson pretty much wrecked Dave Herman at UFC 146 back in May 2012. It was the first bout of an impressive three-fight knockout streak for Big Country, and it took him only 51 seconds to earn the Knockout of the Night honours. Herman, at that point, was 21-3, and 1-1 in the UFC. He was a touted prospect, though the Nelson loss would send him into a tail spin that he only came out of this year. When Nelson's right hand connects, Herman drops like a sack of potatoes. That sort of power is scary.
