Bunch

Three receivers clustered tightly together to one side of the formation (within ~3 yds of each other), 1 isolated WR backside, 1 RB. QB usually in shotgun. Creates natural rubs / pick action vs man coverage; floods a quarter of the field vs zone. Common variant: bunch + slot to the same side for a 4-strong look. Pairs with mesh, smash, and snag concepts. In 5v5 flag (also called a Cluster) all three receivers form the triangle — point on the line with a wing either side — with no back and no backside iso; the center stays on the ball as the natural check-down.
