Shogun has been on a steep downward spiral since he won the title, the Jones fight showed him to be a shadow of his former self. He's going along the same path as Rampage / Tito, the guy has been in wars and was certainly the best 205er at one point in time, but that was years ago now.
Sonnen is a class act, great at promoting a fight and certainly delivers win, lose or draw. Wanderlei will be mauled by him IMO, i didnt see Shogun beating him and i certainly cant see Wandy doing it.
