One innovative solution (probably never happen) would be for conferences to leave the last 3-4 weeks of conference play “open” and do like a Swiss-style chess tournament. In these events, players are matched up round by round based on previous results to so that winners keep playing each other. These are useful when there are numerous participants and not enough time to do a round robin. Rematches are avoided as much as possible.
So Ohio State could play 5 conference games, play The Game (unfortunately, it would have to be moved up), and then the Big Ten would set the matchups for the last 4 weeks based on previous results. It could try to give everyone 2 home and 2 away games as much as possible. This would eliminate the need for convoluted tiebreakers. It might be enough to do this for 3 weeks.
This could be problematic for TV and ticket sales, but the Big Ten could designate home teams for each week in November. So Ohio State could be home for weeks 2 and 4 and away weeks 1 and 3. Then, people could still plan ahead in they want to attend games. You would not know the opponent very far in advance, but it would probably be a good team given that Ohio State is usually a good team.
The downside is that the good teams will pick up more losses as they play each other and hurt their playoff chances.
Kind of cool idea, though.
