joe schilling violent KO in a bar, mike perry violent KO outside a bar, roger huerta violently KO'd a D1 offensive lineman in a street fight, ryan hall and matt serra took down, mounted and easily detained two guys until the cops came. all of those on video. there are more on video and infinite stories.
also there are a million videos of amateur and no name MMA fighters destroying regular dudes with a size advantage in the street.
recently, an oklahoma sooners wide receiver almost lost his eye in a fight with a guy in a bar bathoom who he was way bigger than. the much smaller guy also went to OU but was a regular student and had no fights whatsoever, only trained MMA.
I managed to find the videos. Thanks for the background though, I had only ever seen Huerta.
To be clear, my point wasn’t about an MMA fighter beating an average Joe. My point is about the absolute conviction a lot of people here have about an MMA fighter beating an elite striker in a ‘street fight’ context simply because of their understanding of grappling - quite often however basic that may be.
The reality of grappling is that it’s the single best asset of someone in a sanctioned 1vs1 bout, but falls well short (to the extent it should be actively avoided) in street situations where multiple opponents may be involved. Noticeably, 3 of the 5 examples you provided ended the fight with strikes. They’re also the ones who put themselves in the least amount of danger.
