He earned the nickname Turok, as in the game where you hunt dinosaurs.
He was calling out big names past their prime like Cro Cop, Gonzaga and Big Nog.
He dated Ronda who a ton of MMA fans despised. When he fought Lavar Johnson it was anticipated to be a slobber knocker but Schaub put on an amazing wet blanket impersonation. You could hear Lavar talking to him saying something to effect of "C'mon man, let's put on a show". Iirc he was calling for a title shot as when he was certain he would beat Big Nog. His ego to talent ratio is way off, I think this is what really bothered a lot of people. He's just that arrogant guy with a punch able face.
