From the guard. Every BJJ school has that one student who is a big fan of the arm drag from the bottom, and is constantly making a move dangerously close to your back while you are trying to pass his guard. The person Im having problems with is about my height and build, but has really long legs. Now, Ive been doing this long enough to know whenever you make a move in BJJ, you are usually open to being passed or swept, but I dont see it in this move since the legs seem to stay locked. All I can do is try to realign myself with the armdragger and start from scratch (where he will do it again). Any counters or detriments to keep a guy from going for it to often?
