I assume this thread is coming mainly from David kicking the shit out of Evan on the UFC show. There's a couple of things I REALLY loved about that dude. First of all he was very remeniscant of Maurice Smith in how he handled being taken down. Evan is so known for his subbing ability and ground and pound, but did you notice how by keeping calm and intelligently placing his arms David almost NEVER took a clean hit or gave up positioning to lock in a submission? Like Smith against Coleman, he was just cognizant of his body and even in giving up his back, was never in an optimal position to be either subbed or GNP'ed. A lot of guys will talk shit about Evan's inability to sink in the choke, but that had a lot to do with David keeping his mouth wide open if you noticed. His chin at some points was glued to his collarbone and Evan couldn't get beneath it.
Plus, I LOVED his kicks. Even though few of them landed he threw them FAST and HARD. If he would have pressed more aggresively I think he could have scored a KO with them. If he had tied them in at the end of punch combinations, the same. But he threw kicks like a kickboxer SHOULD, not like a kickboxer who absolutely FEARS the takedown. Instead he had kind of a "so what" approach to being taken down, and it worked against a VERY reputable fighter.
Now, in terms of his elbows. First of all they're conditioned and conditioned well. It takes time to develope that razor sharpness, and the mental wherewithall to almost always land with the point of the elbow. Secondly, he twisted his hips and put most of his bodyweight into them if you noticed. They weren't just arm-elbows. In fact he missed one and almost landed completely on his side. He threw them from the guard-top position with reckless abandon, not caring if he smashed the floor or Evan's face to pieces.
I was really impressed with that dude, and hope a lot of guys looking to improve their stand-up and defend takedowns and submissions learn from him.
Koscheck however, all I have to say is....HA HA HA HA HA HA HA!!! You should never lead with your face my man.
