The "get off my lawn" tone is strong with Bill Superfoot Wallace in the original post's video. Do I agree with what he says? No. I think the Gracies were conscious about portraying BJJ in a good light, but I don't think anything was rigged.
Am I going to rage about what an awful person Superfoot is for doing this interview? Nope. He's the real deal and a full contact kickboxing legend, and after his career he has totally earned the right to be a grumpy old man from time to time.
It's like elderly boxers who think kicking or ground-and-pound is "dirty." I don't agree, but with their age and experience, I'm not going to berate them for their opinion.
The issue is what Wallace was saying was completely false.
