Krazy Horse KTFO Prime Wand so I'm fairly sure Pettis could at this point.
No Krazy horse got choked stupid by one of Wand's team-mates, then lied about it in an interview, then the video of him getting choked out got released and he looked like the lying dweeb he is. He never got anywhere near Wanderlei who was just watching his dumb ass from the sidelines.
Back to the thread, Wanderlei has been in street brawls for years and he had a 4-2 numbers advantage, a major size advantage on Pettis, and Sonnen with the kind of style (wrestling) that is terrible for multiple opponents. I don't condone what Wanderlei did but both Sonnen and Pettis would have been in a coma if this actually happened, no matter their big talk.
