As the 2026 high school football season unfolds, USA TODAY Sports has pinpointed the single regular‑season contest that could tip the balance for every program featured in the preseason Super 25 rankings. These marquee matchups pit the nation’s elite against one another, weaving together interstate rivalries and historic feuds that promise to reshape championship forecasts before the playoff picture even forms.
Rivalries That Define the Calendar
In Florida, the long‑standing duel between IMG Academy and St. Frances Academy sits at a dead‑locked 3‑3, while in California the clash between St. John Bosco and Bishop Gorman pits two coast‑to‑coast powerhouses against each other. Across state lines, Bishop Gorman’s encounter with Mater Dei becomes a litmus test for the Nevada program’s quest to finish undefeated in out‑of‑state play, a feat that could catapult its national standing.
Early Tests and Championship Aspirations
Several games serve as early measuring sticks for teams eyeing top honors. St. Thomas Aquinas of Florida meets DeSoto in Texas, offering a first‑hand look at a program that hopes to defend its national crown. In Arizona, Basha’s rematch with Chandler revives a rivalry that echoed last year’s Open Division final, while in Alabama Thompson’s showdown with Central promises to be a defining moment for the state’s emerging contender.
Georgia’s landscape also shifts as Buford prepares to face Grayson for the first time in the regular season, a meeting that could set the tone for the state’s Class 6A race. Meanwhile, Texas’ own rivalry carousel spins with Waxahachie taking on Duncanville, a clash that often precedes the Open Division championship, and Southlake Carroll traveling to Jenks in Oklahoma, a modern incarnation of the famed Red River Rivalry.
Looking Ahead to the Postseason
Beyond individual results, these contests ripple through the national rankings, influencing where teams sit as the season progresses. The outcomes will inform the next iteration of the Super 25 list, determine seeding for regional tournaments, and potentially alter the narrative surrounding programs that have historically dominated their states. As the weeks pass, the early winners and losers will shape the storylines that dominate preseason conversations and set the stage for the ultimate chase: a state title and a shot at the national crown.
