This is the typical Ho-Stack formation. 3 has the disc stuck on the side-line, and we need a re-set from the cutters.
7 will cut break-side to open up the space for 5 and 6 to cut. take note, 7 is also acting as a decoy if the throw is not completed.
As 7 is running to the break-side, 6 is going for the deep for the 2nd option.
As 6 is running to the deep space, 5 is cutting across for the 3rd option. 7 will fill the horizontal stack.
Lets see how the continuation works.
If the throw is completed to 7 on the breakside, 4 will drop back a bit and 6 will continue cutting down the deep. Giving 7 two options
Option 1 is to throw the disc to 4
Again reverting back
Option 2 is a break huck to 6 striking across
Back again to the Ho Stack formation
3 hucks to 6, and then he will look for handler resets after
Back to Ho Stack Formation
3 throws to 5.
5 will either fake a flick and backhand huck to 6, or throw the continuation to 6 striking deep.
