Spread offenses can give defenses real headaches when they decide to shove a bunch of receivers over to one side of the field. Three (or even four) receivers running loose in the same space can cross up veteran defenses. The defense can push defenders over there to match the numbers, but that can leave a corner isolated on the backside. Yet there’s opportunity for the defense in this situation, too. With the right call, the defense can match a bunch of defenders in a web of different assignments to the offensive passing strength, while still being able to help the isolated defender on the other side of the formation.
