Professor Lucas Lepri teaches how to sweep the opponent using the knee shield. Lucas starts with the opponent in his half guard and slides his knee in for a knee shield. He grips the cross collar and uses his forearm to make the opponent create space so he can now place his knee higher up, on the shoulder. Lucas breaks the grip that the opponent had on the pants and pushes that arm down. He now rolls over this shoulder and uses his legs to help elevate the opponent so he can sweep the opponent over.
