This isn't really a play, but its VERY good for getting yards. this is what you do to turn it into a double screen:
1. come out of FL Sccreen out of Shotgun Normal
2. Hot Route the left outside and left inside WR to curls.
3. Hot Route the HB to a drag, and USER Control him.
After the Snap: When the ball is hiked, you should run to the RIGHT towards the blockers, and call for the ball. doing this throws your opponent off because he'll think that your going to the WR, and after 3 times, you can switch off of the HB and control the QB so you can get it to the WR on the screen.
