Bottom two guys of the 3 man stack (here, 4 and 5) clear across giving the appearance that 3 is going to button hook in
The bottom guy of the 3 man stack (number 5) slashes back to his initial spot to get the disc, while the top of the 3 man stack (3) slashes across a bit to set up for a deep strike
5 receives the disc, and at this time 3 is now going hard straight out
If 3 does not get hit with the deep huck, he is prompted to cut in with a pump fake for a large gainer
