RPO Zone Alert Screen

Watch the play side linebacker depth at the snap, if he sprints downhill into the run gap that is your green light to bail into the screen Identify one high safety shells presnap since single high defenses tend to bring an extra run defender into the box, making the screen the higher value read Track the corner or overhang defender assigned to the screen side, if he sits flat footed and reads run first the screen has room to develop User controlled defenders sitting on the screen or flashing down early into the flat will blow this up before the blockers get set, so have a run alert ready if that happens Zone blitzes and contain blitzes that account for screens with a spy or scraping linebacker tend to shut down the perimeter throw, forcing you to trust the interior run fit instead
