Assume the normal 3-man zone position. Force to the weaker of the sideline handlers.
When the disc is swung to the sideline handler the cup follows. The marker (1) shifts to a hard no-dump position. The rest of the cup (2 & 3) adjust accordingly. The wing (6) joins the cup, preventing any sideline throws.
If the sideline handler gets a throw off, it is likely going to be between (1) and (2) in the cup or a bullshit scoober/hammer throw. These are throw we want to force them to make. These are hard throws that result in hand blocks and throwaways.
If the disc escapes the sideline trap then the 3-man cup chases it, the wing drops back to he regular position, and normal our normal zone play continues.
