The Diagonal Roll out of bounds play from the box set is a simple play designed to get an easy and open layup.
When the official hands the ball to O1, O5 sets a diagonal screen for O3. O3 fakes as though he is cutting to the wing and then uses the screen to cut hard to the weakside low block area. O5, after setting the screen, will roll down the lane toward the basket on the ballside.
While O5 is setting the screen for O3, O4 should break hard to the ballside corner to create an opening for O5’s roll to the basket. O2 releases to become a safety valve.
O1 can make the inbounds pass to either O3 or O5.
