Stick

Check pre-snap safety depth, since two deep safeties signal Cover 2 and the flat route becomes the built in answer against the corner defender squeezing the sideline Watch the underneath zone defenders at the snap, if they immediately widen to the flat routes the corner breaking routes will have a clean throwing window behind them Man coverage with no safety help over the top gets exposed by the corner routes creating natural separation against trail technique User controlled defenders sitting in a lurk position over the flat can jump the underneath route, so know when to reset to the far side corner route instead of forcing the primary read Blitz looks with man coverage behind them are where this concept struggles most since the quick game timing gets disrupted before receivers finish their breaks, so check protection or hot route the flat route into a quick option against extra rushers
