The Pro-Hop is one of my favorite moves to use when finishing  at the rim. This move works great when the defender is lounging for the ball attempting to get a steal. Check out the video below.

 

The player starts by attacking the rim, jumping off of two feet changing their course of direction while in the air. It is important to land on both feet when finishing the lay-up, so it is clear that the player isn't taking extra steps.
