My Power Ratings are generated based on the metrics I find most important when researching games and match ups. The Ratings combine a variety of factors on offense, defense, and also strength of schedule or opponent strength factor in.
The Ratings do not necessarily reflect my personal thoughts on a particular team. One team being currently rated higher than another on a particular week does not mean I personally think that team is better than some of the teams that are rated lower in my Power Ratings.
Strength of Schedule is strongly factored in so teams who play weaker schedules are not going to be rated as high early, especially in College Football. The Ratings will catch up with those teams as they begin playing the tougher portion or heart of their schedule.
