I'm gonna call this pass the "Hot Knife" pass. Matter of fact i'm going to call Rafael Mendes "Mr. Hot Knife" from now on.
If you need some help with your guard passing, this video and and the drills covered within it will make your day. Mr. Hot Knife does a superb job of breaking down the elements of this knee slide pass and covers the smallest of details that will help you pass through your opponents guard like a hot knife through butter. Yes, this video and Mr. Hot Knife are that good. Take notes and go drill.
