That's basically how I meant it, too, clapping_tiger. Kenny got in a good shot when he had the opportunity to do so. Good, that's what fighters should be doing, right? But he was lucky that it did serious damage and came at a fortunate time. Like others said, I think Chris won the first round and would have won the second as well, had that elbow strike not stopped the fight. It did not look like Kenny was going to win that fight at all. It was that one damaging elbow strike that caused the doctor stoppage. Without that one strike, I doubt he would have won.
I have to say that it was interesting to see a fight that was primarily striking. I think all the other fights have been on the ground most of the time, so this was a nice change. Though I think they did say that Kenny had a background in BJJ, so I was a bit surprised that he stuck with the stand-up striking instead of trying to take the fight to the ground more often.
Others do have a point about some people making it this far without fighting, but I suppose under the show rules, there's not much to do about it. It was kind of interesting that they decided to have teammates fight each other in order to guarantee one person from each team would be in the finals. Considering that like half of one team got transfered over to the other, does that really matter at this point? *shrug* I think it's a bit odd to leave the aftermath of each fight until the following episode, but I guess that's one way for them to keep the viewers interested and tuning in.
