Double Cross out of Spread Y-Flex Wk deploys two crossing routes at different depths, with the outside receiver on the left running a deep corner route to clear the top of the defense. The inner slot runs a deep crosser at roughly 15 yards while the TE runs a shallow crosser underneath it, creating a natural high low crossing combo through the middle of the field, and the right outside receiver runs a quick out to hold the flat defender. This is primarily a man beater thanks to the natural picks created by the two crossers, though it can also work against zone if you read the underneath defenders and hit the crosser that settles into the open window. Primary progression starts with the deep crosser, works down to the shallow crosser underneath, then checks the flat route on the backside if both crossers are covered.
Key the middle linebacker depth at the snap, if he sits shallow he can jump the underneath crosser and disrupt the timing of the whole concept. Watch for a user controlled safety sitting in the deep middle, that player is the biggest threat to the deep corner route and the deep crosser working to that side. Cover 3 with a hard sitting curl to flat defender can undercut the shallow crosser, so look for that defender staying flat footed instead of matching motion across the field. Man coverage with no help over the top is the ideal shell to attack, since the rub created by the crossers will beat man to man matchups consistently. Blitz packages that bring extra pressure off the edge can shut this down quickly, since both crossers take time to develop, so identify pre-snap blitz indicators like walked up linebackers or slot corner blitz alignment.
Pre-snap, identify if the defense is showing single high or two high safety look, since the deep corner route on the left can take the top off single high shells if the safety bites on the crossers.
Against man coverage, let the crossers work through traffic before throwing, the natural rub created by the shallow and deep crosser combo will separate defenders trying to trail in man.
Use hot routes to convert the flat route into a hitch if you are facing a hard corner press look, giving you a quicker outlet against aggressive man coverage.
This play pairs well with Inside Cross and PA Y Cross in the same set, since all three attack the middle of the field with crossing concepts and force linebackers to guess run versus crossers on early downs.
Best called on second or third and medium situations where you need a defense to bite on shorter routes so the deep corner route and deep crosser have room to work behind them.
