Any boxer, muaythai, or bjj guy like to give your take on how you would handle such a skilled street fighter? (if theres such a thing as a "skilled street fighter"

Afterall, wouldnt this be the kind of typical street situation that really puts one's art/training to the test?!
Id say it takes at least an intermediate level ma guy to take him on. Most ordinary ma guys would probably be bashed up by a mean street dude like that, and then wonder what went wrong with all those training!
P/S: the black guy looks a pretty good all-rounder?..punching, clinching, ground..crude but maybe with some training, he has potential as a mma competitor?! lol
