He defeats Brian Stann and then subsequently calls out Anderson Silva for a rematch.
It was one of the best post-fight moments in UFC history if not the best moment. Sonnen even took it to the next level and tried to get Silva to raise the stakes. Sonnen wins and Anderson leaves the division. Silva wins and Sonnen will retire from the UFC for good.
So what professions could be good for Sonnen if he loses to Silva?
