To see how a new development can affect the future, look at how it would have affected the past. That’s one of my things – see: how bigger playoffs would have worked in 2020, or how a much bigger, earlier playoff would have affected things – and with the news that we could soon move towards a 12-team playoffs We have a reason to dive into that well again.
For all the simulations I have done, I had never really put much emphasis on a 12-team format. An eight-course meal – six conference champions with two big bids – has long seemed perfectly inclusive and interesting to me. That was the logical next step. But as it turns out, a 12-teamer works quite well in terms of political calibration.
A playoff with 1
However, to best learn about what a 12-teamer changes, let’s jump into the simulation machine.
Below is how each of the last seven College Playoffs in the playoffs would have taken shape with 12 teams instead of four. I used the playoff committee’s ranking as they existed – there is a clear possibility that the committee views teams differently with a 12-team cut instead of four, but we do not know what the changes are for a while. I also worked under the aforementioned assumption that the quarterfinals take place in four New Year’s six bowls, with the semifinals taking place in the same bowls that hosted the four-team semis. I simulated each playoff using my SP + rankings, and I include each playoff team’s odds of reaching the semifinals below as well as the most likely champions each season. (Why semi-final odds? Because I want to see what may have changed compared to the four-team playoffs that we actually got.)
