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 from this past week:
– Colquitt County topped Roswell in convincing fashion to win not only a second straight Class AAAAAA title, but a small trove of accolades from the computer as well:
- For the second year in a row, Rush Propst guided the Packers to a rating of over 100.00, which is the rating required to win 91.5% of all games in an infinite round robin tournament against all teams in the highest classification.
- Only 58 teams since 1948 have finished with a rating of over 100.00 and only ten times has the feat been accomplished in back-to-back seasons, including the 2014 and 2015 Packers.
- This season's team is also the highest rated Colquitt County team of all time, edging out the 1994 incarnation coached by the legendary Jim Hughes.
- Overall, the 2015 Packers clock in with the 15th highest rating of all time while their 1994 team is now 18th and last year's team is 26th.
Interestingly this year was also the highest rated seasons for Roswell and Mill Creek as well, both handily defeated by the Packers over the last two weekends. All three, along with a strong Grayson team, entered the semifinals undefeated before facing each other.
– Allatoona downed Glynn Academy in a close game to claim the AAAAA title. Allatoona was upended by East Paulding to open the season in what ended up being one of the season's least likely results, but then won 14 straight to close the season.
– Cartersville took the AAAA title by denying Buford their fourth straight. Both teams entered the championship game after having played relatively weak regular season schedules, but dominated each of their playoff opponents, including Buford's 35-18 defeat of previously undefeated Woodward Academy and Cartersville 38-7 drubbing of previously undefeated Bainbridge.
- Now, if there's any team that can complain about the computer underrating them, Westminster is it. The Wildcats, who started the season 3-4 before winning eight straight, were projected underdogs in each of the five rounds in the playoffs! Their amazing finish in the championship game only parallels their amazing finish to the season.
But although their rating has improved by nearly three touchdowns since the end of the regular season, the computer still can't quite overlook those early season losses and places Blessed Trinity and Calhoun ahead of them in the final ratings.
Still, I'm sure a quick glance at the trophy case soothes the sting :-)
- Pace Academy also played the underdog role for the last two games to win the AA championship. The Knights started in the semifinals by avenging their regular season loss to Greater Atlanta Christian and then routing Fitzgerald in the title game. They also achieved the highest rating in their school's relatively short history by two touchdowns. However, on the season as a whole, Greater Atlanta Christian edges them out in the final ratings.
- Clinch County is the third team to avenge a regular season loss in the championship game with a 24-7 victory over Irwin County to claim the Class A-Public title. From the start of the playoffs the computer pegged the Panthers as the favorites, but their eventual pairing with Irwin County, a fellow region member who had defeated them 28-12 in the regular season, made for an interesting rematch.
- Eagle's Landing Christian cruised to a 35-14 win over Aquinas in the Class A-Private championship game. ELCA faced the toughest schedule in Class A during the regular season, playing AAAAA Stockbridge, AAAA Woodward Academy, and AA Greater Atlanta Christian, all of whom were legitimate title contenders in higher classifications.
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 0.10%.
For the current season, the ratings accurately account for the winner of 2,045 of 2,241 total games including 2 tie(s) (91.30%) and accurately reflect approximately 68.3% of all game margins within 13.10 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.
