Ho Stack set up. "play is called by handler" is called by handler. 1 and 2 are on the home side in this instance. Can easily be run from all three handler positions, regardless of where the force is.
1 and 2 clear out. (but are also looking for a pass if it's on)
Split second later, 3 goes deep...
...and comes under into the acres of space.
If disc goes to 3 (as we hope it does), the cutters are busting into position. 4 makes it looks like he's going to the zone...
...But also has the option to come under. 1 and 2 are getting into position to be continuation.
