Beginning set up is 2 handlers back (1 and 2), 1 handler (preferably with a strong huck) as the Iso (3), and two side stacks (4 and 5, 6 and 7). Handlers will work to get the disc to the iso. Depending on which side of the field the disc is caught on, the opposite rail will go deep. Let's watch...
If the iso catches it on the force side (with some juking/cutting)...
The last back in the break side stack (4) will go deep.
If the iso catches it on the break side (with some juking/cutting)...
The Iso should look to continue break flow. The last back on the force side (6) will go deep.
Here is a good place to fall into a vert stack, call an endzone play, or call a timeout if the mark is stalling and teammates are not in position. Players should read as they push up field and try to push through on the break side to allow for as much open side movement as possible.
score!
If the handler cannot get the disc to the iso...
Fall into a Ho stack (someone should call this) and flow normally
