Breakdown

RPO Alert X Screen is an RPO built off Singleback Doubles Y Off Close that pairs an inside run action with a bubble screen alert to the X receiver. The diagram shows the offensive line and TE working a run block track to the left while the X receiver sits into a quick screen with a blocker releasing out to the flat to set up the wall, and the backside receiver runs a vertical alert route up the numbers. The primary read is pre-snap to post-snap: identify the number of defenders in the box and the flow of the second level defender assigned to the screen side, then either hand off the run or pull and throw the bubble to the X if that defender bites down on the run action.

Defensive Reads

Watch the flow of the alley defender or overhang defender to the screen side at the snap, if he crashes down hard on the run fake that is your green light to throw the bubble. Check linebacker depth pre-snap, stacked or crashing linebackers signal a run blitz look that this RPO is designed to exploit with the screen. Man coverage with the corner playing tight to the X receiver can be a green light for the run since the screen lane may be compressed by leverage. Zone shells like Cover 3 or Cover 4 that keep the corner deep with soft leverage open up easy access to the bubble screen since the flow defender has to respect both run and pass. Defenses that stay disciplined with a spy or scrape exchange on the screen side, or bring extra numbers to the perimeter, can shut this down by forcing you into the run with no numbers advantage on the edge.

Usage Tips

Use your pre-snap alert key on the flow defender closest to the screen side before the snap to decide run or throw. If the defense shows a heavy box with the alley defender crashing hard on run action, pull it and get the ball out quick to the X screen. Against light boxes or defenses that stay home in coverage, trust the run action and let the line work its track. This play pairs well with HB Dive and HB Zone Wk in the same set since all three sell inside run action and force linebackers to respect the run fit before reacting to the screen. Best called on early downs (1st and 10, 2nd and short) when you want a low risk gain and want to bait aggressive run fits into a numbers advantage on the perimeter. Mix in PA Slide or PA Boot Slide from the same formation to keep the defense honest on run action reads throughout a series.
