Did Florida State get screwed? As has been discussed here at length, there are five teams for four slots, with only two teams (Michigan and UW) that would be awarded slots without much argument. And you can make cogent arguments that any of these five could have the truly best college football team in 2023 and the place to decide that question should be on the field. [And Ohio State and Georgia fans could provide arguments to support their inclusion in this "best-of-the-best" club too.]
But next year, the playoff will expand to a third round with 12 teams. That does reduce the possibility that a potential top team is being excluded from a playoff, as is happening under the current two-round playoff of four teams. But we then have a situation much like the NCAA basketball tournament. The more rounds that are played the greater the possibility that a fluke event (weather, injury, bad referee call) can knock out what would otherwise be the top team (the classic 16 seed beats a 1 seed in March Madness - happened twice in 152 matchups). The more you roll, the greater the chance of a better team being knocked out ("any given Saturday"), even if the better team would win if the two teams played a series, not just a single competition.
Let's apply the apply the selection criteria for a 12-team system to this year's teams. The expanded pool certainly removes the problem for Florida State, (and Ohio State and Georgia). But you can also argue that several of the additional participants really aren't the best college football teams (e.g., Oklahoma, University of Mississippi, Penn State, and Missouri - name a few) in 2023 as demonstrated by their losses to higher-ranked teams that are in the playoff. The University of Oregon lost twice to the Huskies, once at home and once on a neutral field -> not a fluke - sorry Duck fans. These additional team really aren't really at the top level. But in these single-elimination games, one of these second-tier teams could knock out what is truly the best team. [But the first-round bye for the top 4 teams will help reduce these fluke eliminations. How long before the TV money becomes too irresistible and it becomes a 16-team playoff?]
