Discussed at the Volokh Conspiracy and elsewhere, Connecticut high school sports authorities want to stop embarrassing scoring margins in high school football games. Winning by more than 50 points is deemed to be "unsportsmanlike," and can result in suspensions for the coach.
That's a lousy approach. If you want to shut down the game, institute a mercy rule. But don't force people to, basically, throw the game. When the margin gets that big, the winning team brings in its second and third string. These players should have the opportunity to play solid football in a real game situation, even if it means they score more points. These players probably want the play experience, and the younger players want to become good enough to earn a starting role. Having them go through the motions, under penalty for playing, isn't going to help them.
