Within their motion, I noticed they were running an interesting, yet simple, secondary series which I will diagram that action below. I really liked the introductory flex type action and what they ran out of it.
The action started out with a reversal and the post setting a back/flex screen for the wing on the guard's side. After running that action they ran two different looks.
The first option they ran was to have the post step out and catch the ball. The point then ran off the post and got a dribble hand off and attacked the paint.
A third action they ran, aside from the back screen, was a point to wing dribble at and back cut. As the wing back cut, the post rose. The ball was passed to the post on the elbow. As the post caught it the back side guard dove and the back side wing filled. The point passed to the backside wing filling the guard spot then down screened the ball side wing who back cut.
