Tough luck, but that's the brakes sometimes. I was rooting for Erik, but laughed like crazy when he got KO'd - not really out of disrespect of any sort, just because that finish was so unexpected.
These two guys were pretty much dueling for the right to enter the WW Top 10 in their next match and one had to come up short. I wouldn't worry about Silva's job, he's still a really, really entertaining fighter. I mean, he dispatches low-mid level competition in a really stellar fashion. Even when he loses to people it is a spectacle. When was the last time someone had that exciting of a fight with DHK or Fitch? Unfortunately he's competing in one of the deepest divisions of the sport and will have to stack up a good amount of wins before he gets another chance to cross that threshold.
I don't know if he really showed improvement, it was hard to tell with DHK's gameplan. Seriously, some respect to Dong because only someone with a lot of balls or a straight up psychopath would utilize that strategy. He wasn't just set on making the fight ugly, he was adamant.
