College football playoff expansion is inevitable. Who should get in?

Advocates for a college football championship playoff may feel vindicated after the inaugural playoff championship game earlier this week. The #4 ranked Ohio State Buckeyes defeated the #2 ranked Oregon Ducks with a decisive three-score victory. They did this after also defeating the #1 ranked Alabama Crimson Tide in the first round of the playoff.

For years, fans of college football and critics of the BCS (Bowl Championship Series) have been complaining that leaving the championship eligibility up to a subjective vote of a committee is inherently unfair. These fans and critics have long proposed a playoff system that would allow more teams to compete for the national title. This year, that playoff finally happened, and teams had to actually play for their right to be in the title game. The fourth-seeded team - a team that would have been left out of the Championship in the previous BCS-selection process - beat both of the teams that would have been in the vote-based title game, and won the championship.

This outcome is still not without controversy. The age-old argument of "our school got snubbed" has not gone away. After watching Ohio State run the tables in the playoff, the coaches, players, and fans of both Baylor and TCU had to have thought "that could have been us!" They may very well be right. Both teams were left out of the playoff due to misfortunes of mathematics. Even though Alabama (#1), Oregon (#2), Ohio State (#4), Baylor (#5), and TCU (#6) all finished the regular season with only one loss, Baylor and TCU had one fewer win on account of having played fewer games. Only Florida State (#3) finished the regular season with a perfect record (and they weren't even ranked #1!).

#4 Ohio State defeated #1Alabama and #2 Oregon to become 2014's national champions.

While the playoff did consist of the four "winningest" teams in the country, Baylor and TCU didn't have an opportunity to win as many games. Part of this is their fault, since the individual schools do have the privilege of setting their own schedules. Had Baylor and TCU scheduled an extra non-conference game (possibly even one against a Division II school), they could very well have been 12-1 along with 'Bama, Oregon, and Ohio State. But they didn't.

Time to get into the "what ifs": what if TCU and Baylor had played (and won) an extra game and ended the season 12-1? In that case, the selection of undefeated Florida State would still seem like an obvious pick for one of the four playoff spots. But the remaining three would have been a much more subjective selection ...
