Interesting discussion I got from another board.
Among the G5, there are six undefeated teams, including four in the American:
Memphis
Temple
Navy
Houston
Houston plays Memphis and Navy at home
Temple plays Memphis at home
Memphis plays at Temple at Houston and hosts Navy.
Navy plays at Houston and at Memphis.
Mathematically, it is possible for Temple to go 12-0 and play either 12-0 Houston or Navy.
Nonconference, Houston hosts Vandy, Temple hosts Notre Dame, Navy plays at Notre Dame, and Memphis hosts Ole Miss.
There are two undefeated teams in the MAC:
Toledo
Ohio
Ohio will likely lose next week at Minnesota. They also have to play at Bowling Green and at Northern Illinois.
Toledo has two nice road wins. Their first game was cancelled, so they only play 11 regular season games this year. They get Northern Illinois at home, and go to Bowling Green.
Toledo and Ohio don't play in the regular season, so conceivably both could be undefeated heading into the MAC title game.
