Wanderlei is indeed a very simple minded person - Sonnen was little harsh and used the word stupid - but in reality, Wand is a legendary warrior with limited sight. Great heart, but so much given to his emotions, he is easy target to Sonnen to do what he pleases.
When it comes to mind games or wording tricks, Sonnen vs Wand is really a matter of a black-belt toying with kids visiting the gym.
