Build a Roster/Depth Chart:

Create a new Google Spreadsheet or Excel file. 

Fill out the roster with the following information:

Name, Age/Class, Height, Weight.

Using your staff, next fill out critical athletic information.

Add columns for 40yd sprint, shuttle run, vertical jump, squat max, bench max, clean max.

Hold a "testing week" to fill out as much information as accurately as possible.

(have the same person timing 40's for everybody - preferrably a track coach if you have one)

Staff Meeting: Depth Chart

Start a new spreadsheet with all offensive and defensive positions on it. 

Fill it out with your best depth chart predictions. Do not talk about potential, this is a "where we are now document". Default upperclassmen up if they have not been clearly beaten out. 

Example:

Wide Receiver:

1. Jim Smith

2. Paul Jones
