Did you miss the part where I said BJJ was effective in one on one fights? Let me ask you one question: Which is more likely in a street fight? You and one other guy square up and fight it out? Or the guy you are fighting has friends. In which case, BJJ will get you totally stomped out by his friends while you are fighting the first guy. It also leaves you no opportunity to maneuver or run if one of his friends pulls a weapon. BJJ is good, but it’s only good in one scenario. That 1-1 with no interference scenario is NOT what a street fight looks like. Any fighting style that depends on going to the ground is not a good style for street fights, period.
