He used to stop by occasionally a long time ago. He taught class one night --he's not really into teaching. But I liked what he taught.
I recall he said (paraphrase), "I don't know very much jiu jitsu, I just do what I know" That stuck with me for some reason.
Junior told us once that Wallid knows like 10 total BJJ moves but he knows them better than you. That always stuck with me.
