Why should you read this book...?
Maybe one item, one sentence might strike a chord and influence you to think a little bit differently about something.
That one item may cause you to make a change in an offense or do something different with your kids, or do something different as a ref. If one sentence causes you to see your calls differently, coach your team a little differently, give one player a little more playing time or another player a little less playing time...
If something in this book results in your being less argumentative or better capable of holding your ground and doing what's best for you...
if one small suggestion makes a change in anything you do, then everything that I have written here will have served its purpose.
