Chris Sanford had at least had 4 fights before TUF 1 and also trained fighters at Cesar Gracie's gym, so at least he knew about MMA and had fought pro. And was only sent home for being one of the weakest fighters there. So not much of a similarity.
Doing Yoga? Fine, but an instructor who's never fought, let alone sparred in his life?
