I traveled to watch the nation's top four teams in the preseason polls, and my in-person impressions of those programs have helped shape how I handicap the College Football Playoff.

Georgia takes down Tennessee a week after losing to Mississippi. The Big Ten (18) is really tough at the top, but really bad at the bottom. Most of the middle is irrelevant for ranking purposes. The middle of the ACC tanked and Louisiana was removed from the ranks of one-loss teams. It was an interesting week!
