Barnett was still thought of as a top 10 HW by pretty much everybody. Plus Cormier mangled Bigfoot Silva right after Silva had destroyed Fedor. That means he has earned a place near the top of the division, and he's marketable not only for those wins but also as the last SF HW champ. I do think he's too small to compete as a top level HW for long though. He has a pretty soft physique and is short. With his wrestling background I'm sure he could cut to 205 without too much hassle.
