Koschek was doing damage control. Serious damage control. Probably at the behest of the producers and Dana.
Bottom line, he laid his hands on another person, he actually grabbed him by the neck. (not even a contestant or fighter, but a medic, there to help people) he grabbed the guy by the throat for Christs sake.
If Josh was a fighter on the show, he would have been kicked off without a debate or second thought. And as a so called coach, he should have been kicked off the show even faster because he should be setting an example. He should have lost his chance at the title. But I don't think the UFC wanted to loose that main event and I don't blame them. So the UFC and Dana did Damage control and put this to rest.
The bottom line is, we clearly saw that Koscheck can dish it out, but he can't take it (sign of all cowards). He complained that Tate made fun of "his guys", well Josh himself has made fun of plenty of GSP's guys, Cody for one. I guess that's okay.
I'm glad he didn't get kicked off the show and loose his chance at the title. But in retrospect, he probably should have. He had no right to grab Tate by the neck, just because Tate's insult was better than Josh's.
