I recommend you do this after the player analysis because you can't pick plays until you know what you have. So don't skip the player analysis because it is critical. 

Start a new spreadsheet document titled: Core Offensive Installation

Ask your staff, according to our Offensive Priorities Statement, "What is the one play we must build our offense around." If we only had one play to run all game long, what would you run?

Hint: Your best run play. (Power in my book)

Then add plays continuing until you have at least 6. Keep going until you have a consensus core of offensive plays. This does not mean that you can't run Power 6 different ways later on.

Continue to list each play like this:

1. Power

2. Toss (or whatever you say)

Next review the Pro-Spread Offensive Plays and either keep or make changes in what you have listed.
