Running back starts with ball in right hand (using the right side-line).

Bags are set-up as shown progressively getting closer to the sideline as you get closer to the goal.  Bags are shown with Triangles.

As Running back approaches the bags they are given a pop from the defender pushing them toward the sidelines.

Running back holds ball to outside.

As a second progression of the drill have defenders standing on the sideline trying to strip the ball out of the right hand of the running back.   

One swipe, then eventually whatever your need.
