This is one of my favorite passes to hit being a Taller Grappler. I can really utilize my length and stay far away from the bottom players legs.
By staying so far back it makes it tough to re Guard. A key point is make sure you smash that bottom leg to the floor and then push through it works a lot better this way.
This is not a slow pass I should be grabbing the hip shoving the leg down and getting my angle all at the same time. The faster you get at the pass the more successful you will be
*Side note I use this pass a lot to take the back
