FBS conference belt

The Pac-12 Belt

A companion lineage restricted to Pac-12: the belt passes to whoever beats the holder, exactly like the real belt, but only games between two Pac-12 members COUNT — and only for the seasons both sides were actually in Pac-12 at the time. Caught it by beating Fresno State on October 10, 2026. Defended it 1 more time since. The conference has also been recorded as AAWU, Pac-10, Pac-8, Pacific; those seasons count here too.

No reigns match “.”

Membership is judged season by season from every game a team played, so realignment moves a team’s games with it. A holder that stays in Pac-12 keeps the belt through any stretch without a game against another member; a holder that leaves vacates the belt on its last game as a member, and it reverts to the most recent earlier holder that is a member of the season it left for. If no one is left to inherit it, the belt retires with its last holder. Days count the offseason; switch to games to measure a reign by belt games only.
