I'm not critical of anyone's gameplan (more like envious), but I am genuinely interested in where the line is. If 15 plays are required, can you still use 1-4 plays for a majority of snaps and sprinkle in the others?
Why 15 and not 10 or 20 or 25?
Why aren't the override penalties enough?
I think we can all agree that using a single play all game doesn't pass the smell test (even if it is realistic: see 85 Bears, Tampa 2, etc.), but everybody abuses some plays on both sides of the ball to some extent. Or they lose.
Setherick and I have been very transparent about utilizing a DB of plays to guide decision making. He manages the DB, and I sometimes ask him for an output — like what passing plays have a median gain of 7 yards and 60% completions. I'm beginning to think I built better plans before the DB, but he does it to keep his SQL skills fresh.
Also, I'm not exposing any secret information about play selection here. This same information is available to your upcoming opponent through the in-game gameplanning screen.
