Tony Dungy's Quiet Strength: The Principles, Practices, & Priorities of a Winning Life is a memoir about Tony's faith and NFL coaching career. His story starts slow but hits a quick pace by the end, where Tony enters some of the most emotional moments in his life: his son's suicide and his Super Bowl season.
I agree with Tony's values, but there's a disconnect between his message and his actions. The demands of his job make it nearly impossible for him to be an effective father. He discusses this in the book and surely continues to struggle with it.
In almost every other aspect of life, Tony is a great role model and his words contain important messages for all Christians, particularly fathers. But fathers should be cautious to do as he says, not as he does. Be there for your wife and children.
