As someone who is stuck in that conference, i can give you some insight into the Grayslake teams and Wauconda:
1. GL North is not nearly as tough as they appear. If you play their game, they will beat you, but if you dictate the intimidation, they can fold. They can pass, but the qb can get rattled.
2. having played both NND and Wauconda, I think Wauconda will do okay because they will throw a bit better than we did, but if NND figures out there was really only one receiver to cover (like GL North did), it's NND in a run-away.
3. Iggy and GL Central won't be entertaining unless you are looking to see a full game and still make a 830 movie
Short story, go see NND/Wauconda maybe but I would go see Carmel, Warren or LZ if I wanted to see competitive football.
