On the line we'll call the play "Stack [direction], iso [name], [2nd name] out of the back]" and possibly a handler to fill in at the front of the stack. So here we have "Stack right, iso 1, 2 out of the back." It's important to get in position as soon as possible and give the handlers time to take free yards.
The iso cutter takes 4-5 seconds to go where they want, deep/under/break.
Here, 1 fakes deep and takes the under option and gets the disc. 2 sets up their cut by attacking towards the middle of the field to get their defender on their heels.
2 fakes under.
And goes deep, receiving a huck from 1.
Alternatively, 2 can fake deep.
Receive the disc from 1.
And go deep to 3.
Whether or not the isolation(and following cut) works, the offense should clear and flow into a normal vertical stack in the middle of the field.
