Base Crack Layers from our 7on7 flag football plays collection is a fairly simple play to run and execute that has several options with easy reads. Lining up in a traditional 2 blocker 3 receiver set, the quarterback sprints to his right immediately at the snap, while the slot receiver steps inside to pick the rusher and allow the quarterback a free lane.  Trails with an under route while the center runs a corner route over the top, and with a defense running a zone ’s dig should come open pretty easily, or if in a man defense, the quarterback has a good shot to get free and run if he’s decently mobile. As a last resort, you can also throw back to your  who drops to star, allowing him to hit  on a stop and go. Or simply have him shoot left or curl if you don’t have a good throwback option.
This play works great for 10-15 yards pretty consistently, but it is definitely dependent on a quarterback who’s slightly mobile at worst, and a slot receiver who can get a good block on the rusher. You can also run alternate routes fairly easily out of the same formation with  blocking for you, or even motion him to the left slot with the stop and go as your primary option and  dragging to the left instead. This is definitely one of the more flexible 7on7 flag football plays you should consider using with the right squad.
