So I've trained BJJ for 2 mos but have prior wrestling experience and aggression and confidence Today I showed a coworker a clip of the Mundial Jacare match and he said, " Not interested" and that Karate is much better and more effective. Before he said he trained karate. So I just demonstrated a RNC on him and he said he would just reach back and punch me. (LOL) He lives nearby so I told him to get dressed and come back and we could spar LIVE for a minute. He eventually said no, and I showed him the Royce and Rickson UFC highlights and Jason Delucia clip. He definately changed his tone after that. BTW - Was it bad BJJ ettiquite to challenge him like that?
