Baseball is a lot like life. It's a day-to-day existence, full of ups and downs. You make the most of your opportunities in baseball as you do in life.
Those who kept their sanity and humanity intact in the face of awful adversity. Heroes named and unnamed, some known only to God.
And the fact that you must make the movie for yourself because no one else will ever fully appreciate the endeavor, makes it a more rewarding challenge.
