I don't think this is the case. Once the fight starts and contact is made, that all leaves and tunnel vision on fighting sets inThat's all good but what happens when you're in top position smashing and all you can hear in your head is.
"you're a white belt on the mat"
"you can't even pass guard"
"I'll butcher you from bottom, then stand up and butcher you on the feet"
You're bat shit crazy if you think Chad wasn't affected by all that, in fact it would take huge mental strength not to try prove those things wrong once you get in a dominant position. If anyone gives him an opportunity to scramble they're fucked.
