The Maxwell Ratings will rank Georgia's 417 teams throughout the 2015 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.
Interesting results after week 2:
- Sandy Creek was shocked by 37-point underdog Jonesboro 17-15 to drop nearly 13 points in the ratings. The shift brought them down from #2 to #7 in Class AAAA. Jonesboro received a nice boost of a full 15 points to land at #10 in the Class AAAA ratings. Still, the ratings would label Sandy Creek, currently 90-7 with three state titles and two undefeated seasons since 2008, as an 11-point favorite in a rematch.
- Washington County, last week's top team in Class AAA, also lost a close game to a heavy underdog with a 49-42 shootout to Thomson in spite of being a 24-point favorite. As a result, Washington County dropped over 11 points while Thomson shot up nearly 13 to debut at #8 in the Class AAAA ratings. However, the ratings still view Washington County, 38-4 over the last three years and last year's state runner-up, as a solid Class AAA contender at #3.
- Perhaps one of the more interesting results in this week's ratings is from the game between Eagle's Landing Christian Academy and Stockbridge. ELCA lost 28-21 despite a late comeback bid against Stockbridge, currently ranked #6 in Class AAAAA in the ratings and #3 in the AJC rankings. ELCA, last season's state runner-up, entered the game ranked #1 in Class A with a rating of 59.76, but dropped a mere 0.01 points with the loss and remained on top. ELCA is 56-14 since 2010, but that includes a 7-7 record last season when the school played a grueling out-of-region schedule including two games against the Class A-Private state champion and four teams from higher classes, all of which were among the losses.
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 56.66%.
For the current season, the ratings accurately account for the winner of 260 of 271 total games including 1 tie(s) (96.13%) and accurately reflect approximately 68.3% of all game margins within 13.15 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.
