Division standings are based on each team's overall conference record. In the event that two teams are tied, head-to head competition would break the tie. If the two teams did not play, division record will be used to determine the divisional champion.
If three or more teams are tied, the following tiebreakers are used to determine the divisional champion:[1]. The following procedures will only be used to eliminate all but two teams, at which point the two-team tie-breaking procedure (head-to-head result) will be applied.
- Head-to-head (best record in games among the tied teams).
- Record in games played within the division.
- Record against the next highest placed team in the division (based on record in all Conference games, both divisional and non-divisional).
- Record against the next highest placed team in the division (based on record in divisional games).
- Record against common non-divisional opponents.
- Best overall winning percentage in all games.
- Highest CFP ranking following the last weekend of regular-season games.
- Coin toss.
Guess they could come up with something buzzard but it looks like they have a framework.
