Tight Splits
Compressed — receivers near the formation.
Receivers aligned inside the numbers, close to the box. Compressed splits shorten the field for crack blocks and turn every receiver into a run-game participant.
What it does to the defense
Run fits: crack blocks on safeties and force defenders. Safeties have farther to travel to their landmarks — and when they creep up to help, play-action goes over their heads.
How each scheme uses it
Air Raid
Compressed mesh: shorter throws, bigger rubs, faster separation.
West Coast
Drive and shallow crossers from tight splits — everything breaks closer to the QB.
Power Run (Gap)
Crack toss and counter: the safeties get walled off by stalk blocks.
Wide Zone
Tight-end crack seals the edge; bootleg away from the compressed side.
Spread Option
Speed option to the crack side with the alley defender walled off.
Vertical
Play-action deep overs behind safeties who crept up on the compressed looks.
