Yan is a far worse champ. Idiot threw a blatant illegal knee and whines that he got DQ'd. Champs have to lose their belt if they get DQ'd or any champ losing will start eye gouging, biting, kicking to the head of a downed opponent etc to keep their belt.
Yan won a vacant belt against an Aldo that was coming off a loss. Why is everyone acting like Yan is a BW God? He is 15-2 and Sterling is 20-3. Sandhagen is 14-3 (should be 15-2 same as Yan) since the Dillashaw decision was BS. I am good with Corey vs Petr for an Interim Belt. In fact I wish the UFC would have had a BW GP to crown a new champion.
Maybe Yan could win the belt and defend it a few times before all this BW God talk.
