Pretty good lists. I think Phil Davis is underrated here. He's beaten Gustafsson who is higher on the list and would beat Silva, Griffin, and Jackson. Frank Edgar probably shouldn't be listed as a lightweight and having Nick Diaz ahead of Carlos Condit reeks of personal bias since Carlos just beat him and pushed GSP to the limit. Bisping is ahead of several fighters he's never fought but I'm inclined to keep him above Belcher due to the Akiyama fights they've each had but below Belfort who's recent middleweight resume is more impressive. Ian McCall might be too high on the list as well--I think Beefcake, Dodson, and Cariaso could beat him--but I understand putting him second since he pushed Johnson in their first bout.
