Something changed inside the Ohio State locker room coming out of November's loss to Michigan, a setback that ignited a historic run through the expanded College Football Playoff en route to a national championship.

As it stands, this will be the third different playoff system for college football in the span of three years.

Those seeking parity during college football's 2025 season have come to the right place -- at least glancing at under-the-radar games with the potential of playoff-altering upsets. There's more than a dozen non-conference matchups early this fall that could move the needle nationally depending on the result before league title races commence in October.
