From the same tournament, watch The Mechanic jam. One power jam, he's about 20 feet from the back of the pack, and calls out whilst swinging his arm across. His team sweep over from their conga-line and blanket the defence, giving him an unopposed outside line. Presto, 5 points based on teamwork offence rather than a jammer going 1-on-4.
The sign of a poorly managed team is when they run a play time and time again, and still see no results from it. However, there probably isn't time in a bout to have a proper think about whether or not to use this play, so I expect most teams will use it as a first-choice. If it works for you, great! Keep it up! Be brilliant!
There are thousands of minds thinking about derby in the UK alone, each coming up with slightly different answers to the same problem. The beauty of the game is seeing that myriad of solutions played out on a 160 foot oval surrounding a white board.
