Im with you on this one. Every other sport gets a chance at post season play. Why not do it with football. Cut back the non-district games and just play district games. Non district games are worthless. A lot of teams have their "suspended" players sit during those and then they are back for district action. Then at the end of the season you match up the teams for playoffs. You can still have enough games for student athletes to play in.
I understand what you are trying to say with your "worthless" comment, but many times rivals are not in the same class or not put into the same district by the state. Schools would not want to do away with these games and the atmosphere/$$ they bring in.
I wouldn't want rivalries to die simply for the sake of getting every team into the playoffs.
