How was he the champion in the UFC?
He fought 3 times in the UFC & lost 2.
Loss to Belfort.
Loss to Tito.
Win over Tony Peterra.
Are you saying that the Peterra fight was for the UFC title?!?!?!?
Actually there are a lot of people who claim to be world champions in the UFC. Ian Freeman has claimed to be an ex-UFC champion, although to my knowledge he's never won the title. So maybe it's cos Silva won a fight in the UFC he's regarded as a champion.
I don't know, but it's BS. Wanderlie Silva has never been a world title holder in the UFC. Period.
