Start with the disc on the sideline, the first thing that happens is 4 makes a clear cut out
As they clear, middle handler cuts hard up the line, as this happens 1 is striking deep
If the pass to the handler is completed, we throw a deep huck to 1. (4) clears to the stack somewhere between 2 and 3
If no pass is thrown (as is the case here). the handler (6) cuts back to the middle of the field. The farside handler (5) is cutting up the line, mirroring (6) and (1) is cutting under while (2) is cutting deep. This is the toughest step as everyone is involved!
The pass was thrown around to (6). The thrower also could have thrown to (5) who would have then hucked it to (2). Seeing as the pass was thrown around to 6 we are now looking to swing across to (1)
Continue to (2)
