I don't believe in team motivation. I believe in getting a team prepared so it knows it will have the necessary confidence when it steps on a field and be prepared to play a good game.
Trust your gut instinct over spreadsheets. There are too many variables in the real world that you simply can't put into a spreadsheet. Spreadsheets spit out results from your inexact assumptions and give you a false sense of security. In most cases, your heart and gut are still your best guide.
