Have you, or have you seen anyone use this while rolling? I ask because I remember watching a Rich Clementi fight (I think it was against Melvin Guillard), and he uses a full nelson from the back for a few seconds. I thought it was interesting because I've never seen it before. I use half nelson and quarter nelsons all the time, but I've never attempted the full nelson. I know it's a pretty effective neck crank if done right (I think that's why it's banned from wrestling, but correct me if I'm wrong). Is this a legit move, or just a gimmick?
