I am not going to list a bunch of fighters but the answer is simple. Anyone who hangs around the top 10 for the last 3-4 years but never goes near title contention. And fighters who are in slug fests and put on entertaining fights, the Stout's for example.
The only fighters you will really see cut in the near future are the bottom of the pack fighters, especially if they go on a 3 fight losing streak, like John Howard. At the end of the day, Dana like the lower end fighters to leave everything in the cage, go for the kill or die trying, and if you do that, even if you dont ever crack the top 10-15, you will have a job in the UFC.
Just an example... Dan Hardy is not UFC's boy for Britain, it's Bisping. He went on a big losing streak, losing horrible in all the fights, yet he is still around and John Howard is gone. Case dismissed.
