Building off the reshot we looked at last week this class focused on finishing the sweep single. The sweep single was designed to counter the sprawl. It moves us to the side and away from the power of our opponents hips. That said, it does not require the sprawl. If we shoot and sweep and they do not sprawl, great, wrap build back to your feet and run the pipe. But, if we shoot on a single and do not sweep and they do sprawl things get hard fast. No one likes to be bottom front headlock. We did not spend a ton of time on the mechanics of the shot for the sweep, instead focusing on the finish, but here is Kolat with the one minute version.
So if we shoot and sweep and they respond with the sprawl, now we got ourselves a fight! This is the meat and potatoes of freestyle wrestling. in Jiu Jitsu I tell people to make sure they get comfortable in half guard because you are going to spend a lot, A LOT of time there. This is the wrestling equivalent. Expect them to sprawl when you shoot and expect it to be a fight to finish.
The mechanics we looked at focused on shelving the leg to the outside hip. In wrestling this serves mainly to steal base from the leg and to hold it in place without your hands. In a Jiu Jitsu, sub only, or combat wrestling context it also serves to essentially put us in leg drag, preemptively passing the guard should they choose to turn back in. Once shelved, we build and gather on the far leg making a special point to stay below the hip so as not to feed our opponent a live whizzer and again risk ending up under front headlock.
