Football Teams of last 40 Years

Hanging in the hallway at one high school are the basketball team pictures from the past 40 years. A player in the center of the front row in each picture holds a basketball identifying the year -- "62-63," "63-64," "64-65," etc. One day a new student was looking at the pictures, and was heard to enguire, "Isn't it strange how the teams always lost by one point?"
