Let’s treat him seriously.
He’s a professional. Why I bet he’d last about 1.5 seconds longer with a professional MMA fighter than I would.
I’m not sure what you mean, by “let’s treat him seriously”
I don’t see any comparison to MMA at all, where head butts are banned, and competitors need to be well rounded in many disciples including wresting and submissions. This is street survival fighting. Of course people are going to have opinions as to whether or not these are good techniques or not. Sure he probably couldn’t beat a professional UFC fighter - couldn’t beat a .45 double tap to the chest either - so?
