I've been following MMA for years now and the guy on the bottom normally does one of three things. Submission, stand up, or hold on for dear life. I rarely see sweeps and Im wondering why you think that is the case. I don't see too many elevator, scissor, cross body, butterfly sweeps. And those don't need the gi either. Of course there are few exceptions like Carlos Newton cross body sweep Pat Militech but its not very often. What's your take?
