Playing up is fair question for debate.Great matchups for the title? Of their 9 titles Only Morris, RB, and Geneseo have kept the final within one score. They have outscored opponents 337-201 in the title game.
No team in 4A challenges them in the playoffs. In all of their playoff games in seasons where they won the championship, excluding the title game, they have had a total of 2 playoff games decided by one score; 23-21 over QND in 2010 and and 48-47 over Althoff in 2016. So, in all of their title runs, including the title games, they have had a total of 5 out of 45 playoff games decided by only one score.
Rochester has won 9 titles in 13 years, 8 of those being in 4A. Yes, they should be playing up, but Derek prefers to be a big fish in a small pond. Nothing at all wrong with that, but people will always question success and why they don't petition to play up.
However, the vast majority of title games don't meet the 1-score standard you cite in Rochester's wins. In the last three years, only 4 of the 24 title games (17%) have been decided by 7 points or less. The average margin of victory in the title games last year was 24 points, 21 in '22, and 19 in '21. Rochester's average winning margin has been 15 points.
If perennial title winners like Lena, Wilmington, Byron, and Rochester played up, you would get some different teams winning titles but there's no guarantee that the results of the championship games would be any closer.
