I'm very happy to be mistaken. I was a casual fan in college, but the worm turned for me when I started hanging out with my brother in law who plays at Ball State. Hearing someone accurately predict what's going to happen before the ball is snapped, and then explain why (e.g. "they ran it up the gut because the linebacker had his weight back on his heels") really opened my eyes to the depth. If there's any HN football fans out here in Denver who'd like to get together one weekend to watch a game, I'd love to meet up!
