What's the opposite of a barn burner in football? Wisconsin vs. Iowa might show us exactly what that looks like. It is setting up to be a day full of punts, not points, and it might be really boring football. This isn't to say a defensive battle is boring football; in fact, the average Wisconsin or Iowa fan would argue that it's great football.
This game won't display great defenses; it was instead a showcase of bad offenses. Whatever punt contest this turns into won't be because the defenses are amazing; it will simply be because the offenses can't get anything going, especially if both teams feature the backup quarterback.
