Trigg does try too hard, when he is just being natural and not being the dominate speaker it works. I really like Rogan, he is the only one willing to go "out of character" and talk like a real person from time to time. Plus he is a great improvisational comic, and those skills shine through.
Rogans the best of the worst in the UFC. This guy did nothing but gas Liddell up for 4:59 of the first round then turns around and states that Chuck should retire.
I like Rogan's sense of humour, he often makes me laugh during the broadcast which I like. Goldie is average at best but UFC isn't UFC without hearing "It's aaaalllll oooovvvveerrrrrrr!!" when someone get's knocked out. Mir and Randy are both good too. As long as they keep Tito away from the mic I'm not too fussed.
