Another thing a limited playbook allows is a deeper understanding of the plays by the players. Some coaches don’t like to explain these adjustments to teams. We are the opposite.
One of the easiest traps for offensive coordinators to fall into is having a bloated playbook with a vast number of plays that have no real connection to each other. Throughout a season it’s easy to add one to two plays a week and end up with a gigantic playbook, while still not having answers for the typical defensive adjustments that they will see from their opponent.
In order to be successful it’s critical that the offense has a streamlined playbook that allows the players to master their skills instead of spending time working on the schemes. The limiting factor of all football teams is time. No matter the level there is a finite amount of practice time.
