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 of the preseason ratings:
- As might be expected, Region 1-AAAAAA starts the season at the top, however it’ll be interesting to see if it can stretch its 30-0 regular season run from last season. Using the preseason ratings, the region has a 4.95% chance to go 26-0 against its in-state out-of-region contests (the Maxwell ratings do not have enough data to accurately rate out-of-state opponents). That’s the same chance a coin weighted to come up heads 89.1% of the time has of getting 26 heads in a row.
- However, the question of whether the region can go undefeated may be answered early when Valdosta plays Norcross in the Georgia Dome on Saturday. The Wildcats are a 6-point underdog to the Blue Devils in the only game the Region 1-AAAAAA team is not favored. Colquitt County also plays North Gwinnett in the same venue and Lowndes visits Roswell Friday to account for the region's three toughest outside games of the year right out of the gate. The good news (for Region 1-AAAAAA fans, anyway) is that if the region can go undefeated in Week 1, it stands slightly better than a 25% chance of finishing the regular season undefeated.
- Games involving Region 1-AAAAAA are not the only big games on tap, though. McEachern plays Tucker in another top rated matchup of the season. McEachern is favored by 2 in a rematch of one of last year’s quarterfinal games.
- Benedictine hosts Greater Atlanta Christian in what could very well be a preview of the Class AA state championship game. In fact, the preseason ratings show there is a 13.24% chance these two teams will face each other in the state championship, the highest of any regular season matchup. The Colquitt County-North Gwinnett game has an 8.00% chance of being a Class AAAAAA state championship preview.
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 100.00%.
For the current season, the ratings accurately account for the winner of 0 of 0 total games including 0 ties (--.--%) and accurately reflect approximately 68.3% of all game margins within --.-- 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.
