True but at the same time, knowing MMA doesn't exactly mean one can hold their own in street fights. People forget that MMA is a sport, not a fighting style. Yes, one would definitely want to be skilled and well rounded, but what works in an MMA match won't exactly work in a street fight. Two totally different environments, one is a controlled setting with you, your opponent, and the ref, while the other is a bunch of uncontrollable variables and often chaos....anything goes. A bunch of these cats going out there taking MMA classes thinking they're gonna be an untouchable badass in the street often this out the hard way cuz they have no idea how to put any of their training together in a street fight, nor have most likely not even been in any since perhaps childhood. Dudes in the vid obviously had no idea what they were getting into nor have been involved in many street fights because anyone trying to pull jiu jitsu in a fight where there's hella ppl involved is fukking retarded. There's no ref, you're nothing but a target while you're trying to grapple on the ground, so who's gonna stop ol dude from kicking a field goal with your dome?
