Yeah, I'm not trying to say the sport didn't continue to evolve after Gracie, but it seemed like before he came along the fighting was almost just a no holds barred slug fest with little to no strategy aside from knocking your opponent senseless or tackling him and then beating him senseless. Then this dude comes along, practically out of nowhere, saying how he can beat anybody with strategy instead of force and then he actually does it. Definitely a testament to BJJ's effectiveness in my opinion. Although it was by no means the defining point where ground fighting became a viable tactic. It just seemed like a point that generated a lot of attention for that style of fighting and kind of caused some people to reevaluate their defensive strategies/fighting styles.
