Before the pull, everyone agrees: force forehand. The mark (D1) steps to the backhand side; every other defender moves to the forehand side of their cutter.
O4 cuts in on the forehand side. D4 runs with them, a step closer to the disc, so the lane never opens.
O5 cuts to the backhand side. D5 lets them go: a throw there has to get around the mark.
The thrower pivots for the backhand to O5. The mark shuffles across to stay on that line instead of lunging. No around.
O6 goes deep down the forehand side. D6 turns and runs on O6's deep shoulder.
Stall eight: the only throw left is a forehand into the lane D4 already owns.
Block. One rule, seven defenders, one side of the field to cover.
