Mir is being underrated in this tournament. He went on a bad losing streak but you have to consider that it was against a murderer's row and he was the underdog in every fight. JDS, Cormier, Barnett, Reem, Arlovski, Hunt. All of those guys are currently ranked in the top 10 except for Arlovski and that fight was during Arlovski's resurgence when he was on the verge of getting a title shot. Ask yourself how well any of these other fighters in the tournament would do against those guys. If Mir were fighting the bums that Fedor and Mitrione have been he'd be on a win streak too. You can look at Mir's last 8 fights and see the two times he took a step down in competition he got a first round KO. I don't think that's a coincidence. I think he has had a similar skill level the past few years, the problem is he's been fighting guys much better than him and losing fights he is supposed to.
Fedor is a shell of his former self and getting hurt by every clean punch these days. Sonnen is too small and vulnerable to submissions. Mitrione has no ground game and seems to be getting rocked in every fight now. I think the finals is gonna be Mir v. Bader and I'm not sure who wins that one.
