Every team has that one staple play, one they execute better than any other play in their offense, and becomes associated with their offensive scheme. In the air offenses around college (and 1 in the NFL), that play is simply “four verticals.” And since every team copy’s the best plays from other teams (like the infamous Shanahan end-around), even non air raid teams are running four verticals.
Four verticals is an air raid staple where the receivers all run downfield on vertical routes. There are nuances to the play, though. Any receiver has the ability to stop his deep route at 10 yards and turn to look for a pass.
