Great stuff! A lot of Black belts like to get in the fetal position and then wait for you to come in and then they do nothing until you are off balance and then jump into action. I think it hurts all involved as the person on top can't practice passing guard, legitimate submission opportunities and has to take all of the risks in order to go after a submission. The bottom person waits for you to be off balance, which will inevitably happen, and then jump into a sweep. It gives them a false sense of security that it is a great tactic, but it can't be used in any situation other than the home gym. - (As a Brown belt) I've found that I can usually stay on top of a person and maintain it for a round and also do nothing, but when I legitimately try to go for subs, it will eventually put me at a disadvantage and I will get swept because I am playing the bottom person's game (just because I don't want to stall as the bottom person is doing).
