Pull goes up.
Cutters set up a vertical stack on the same side of the pitch as the pull drops. One player (assigned on the line) sets up iso-ed in the middle of the pitch.
Pull is centered immediately. Main stack stays wide to leave space. Iso-ed cutter sets up the under cut by driving their man deep.
Iso-ed cutter turns and takes the under. Stack is in motion looking to take advantage of any poaching and strike deep.
Score!
