In sport bjj, who have you never seen pull guard? I don't think I've ever seen Jacare pull gaurd with the gi on unless he was going for a flying submission. I know he pulled guard against Marcelo in adcc and against Randy Courture, but that was a specific strategy.
Royler, Mario Sperry, I thought Terere until I saw some of his recent absolute matches. Who else? Anyone you've seen compete who never pulls guard?
