The landscape of high school football in the CIF San Diego Section is getting a significant facelift just in time for the 2026 season. Following the release of the Section's latest postseason structure adjustments, it is clear that the road to a championship will look very different next fall. From divisional realignment and playoff seeding changes to a new competitive balance formula, the Section is implementing some of the most impactful football reforms in recent memory.
After a successful debut in 2025, MaxPreps will continue to serve as the official ranking system used to seed the San Diego Section Championship brackets, maintaining continuity while the postseason structure around it evolves.
One of the most noticeable changes comes in the makeup of the playoff divisions. The Open Division will remain an exclusive four-team field reserved for the Section's elite programs. Division 1, however, will shrink from 12 teams to just eight, making it even more difficult for teams to earn a spot in one of the Section's most prestigious brackets. Divisions 2, 3, and 4 will remain at 12 teams each, while Division 5 expands from 12 to 16 teams, creating more postseason opportunities for programs across the Section. The move appears designed to increase participation while preserving the competitive integrity of the upper divisions.
The playoff bye structure is also receiving a significant adjustment. In Divisions 2, 3, and 4, the top four seeds will continue to receive first-round byes. Division 5, however, will operate differently. With the bracket expanding to 16 teams, every team will be required to play in the opening round, eliminating byes altogether.
The Section also clarified that the top 16 teams in the overall San Diego Section rankings will earn first-round byes during the postseason structure, creating an added incentive for teams to finish as high as possible in the rankings.
Perhaps the most significant change is the introduction of a new Playoff Pool system designed to improve competitive balance. Beginning in 2026, every football program will be assigned to a Playoff Pool based on a formula that incorporates a 70-30 model, enrollment factors, and a school's two-year ranking history. While teams will still be seeded according to their end-of-season rankings, they will no longer be allowed to move down more than one Playoff Pool when postseason brackets are created.
