Last night I was running transitions with a guy that was a serious nerd. Been doing BJJ for 3 years, 200 lbs, my height and the guy would go beyond the drill every fucking time. Then sit there and talk about becoming a jedi master and how cool star wars was. We'd do full mount to transition with the bottom person on side, just to get used to getting your knee all the way up to the bottom person's head and the other foot into their hip. Well anyways, this guy would then proceed to try doing stupid arm bars, locks, etc while we're supposed to be drilling. I beat him up a little rougher than normal when we were rolling just out of frustration, but I don't want it to happen again. Is it lame to ask my instructor not to match me with him even though he might be the only one my size?
