The Maxwell Ratings will rank the Georgia High School Association's 418 teams throughout the 2017 season. The ratings are based entirely on historical performance and on field results and do not consider personnel changes on the roster or coaching staffs.
- Lee County and Tucker have been close in the ratings for a couple of weeks, but the Trojans received just enough of a boost from their 49-0 victory over Thomas County Central to take the top spot in AAAAAA. If both teams continue, they may very well settle the issue on the field since the top region seeds from 1-AAAAAA and 4-AAAAAA start on opposite sides of the bracket this season.
- Although region play hasn't quite kicked in fully for most parts of the state, competition for the At-Large bid in Class AAAAAAA is largely settled by out-of-region games. Here are the front-runners so far:
Maxwell GHSA Football Ratings
As this season's games are played, the Maxwell Ratings will be based on a modified logistic regression of the current football season's results in combination with each team's historical performance. More recent games and games against similarly rated opponents carry more weight and the weight of each team's historical performance diminishes as the team's season progresses.
The current total weight of all team's historical performance is 20.80%.
For the current season, the ratings accurately account for the winner of 901 of 954 total games including 0 tie(s) (94.32%) and accurately reflect approximately 68.3% of all game margins within 12.19 points.
The ratings are scaled so that 100.00 is the rating required to win 91.5% of all games in an infinite round robin tournament against all teams in the highest classification. The schedule strength is the rating required to win 50% of all games in an infinite round robin tournament against a particular team's opponents.

†-Plays non-region schedule
Each region is shown with its “Competitive Rating”, which is the rating required for a new team to that region to have a chance of going undefeated in a round robin schedule among region teams equal to the chance of being selected region champion if picked at random. For example, there are four teams in 1-AAAAAAA, so the chance of a new team being region champion if picked at random is 1 / (4 + 1) = 20%. Therefore the Competitive Rating is the rating required to go undefeated in a round robin tournament among region teams 20% of the time. This rating favors regions with larger numbers of highly rated teams. The “Average Rating” is the rating required to win 50% of all games against the region’s teams in an infinite round robin competition.
