Weekly Playoff Probabilities - Week 13

As always, explanation here, ranking below, thoughts after.

Rank Team Agg Rank POFF Prob Change
1 Alabama 1 80.07% -7.4%
2 Wisconsin 7 72.73% 12.6%
3 Clemson 4 72.47% 16.9%
4 Georgia 5 62.23% 18.9%
5 Miami (FL) 13 30.20% -43.2%
6 Auburn 6 27.52% 22.6%
7 Oklahoma 9 24.43% 10.2%
8 Ohio State 2 11.80% 4.6%
9 Penn State 3 9.83% 4.2%
10 Central Florida 15 3.20% -15.1%
11 USC 17 2.66% 0.1%
12 Washington 8 1.61% 1.1%
13 TCU 11 1.26% 0.8%

1.  So Alabama is still first.  That may seem odd, but it makes sense when you remember that they don't have to play any more games, and thus are guaranteed to finish with just one loss.  Many of the teams below the Tide will leap them should they win next Saturday.  Wisconsin would jump to #1 with a win.  Clemson and Georgia would both pass Bama with wins.  Miami would just barely pass them.  In short, Alabama could be as low as fourth in my final model, but that still means my model tends to think they will make the Playoff.

2.  You may notice that I adjusted Central Florida again.  The committee's consistently poor treatment of Group of Five teams leads me to believe that it will be nearly impossible for one to make the playoff.  This led me to theorize that I should treat UCF like a two-loss power conference team.  This means that their SOS, while quite strong for a non-power schedule, is now treated as roughly equal to teams such as USC and TCU.  The resulting playoff odds feel much more in line with reality.  I will re-visit this in the offseason to determine how to proceed moving forward.

3.  We say goodbye to Washington State and Notre Dame, as they both finish their seasons 9-3.  The Irish's strong SOS (currently projected at .618, which is good for second in the nation, behind only Maryland) would've made for a fun case study for my model.

4.  In case you didn't notice in the first chart, it's now pretty likely that the SEC gets two teams in.  If Oklahoma wins, it'll be a much closer case.  If the Sooners lose, get ready for people to be unnecessarily angry.

Oklahoma TCU 63.9% 0.056
USC Stanford 48.1% 0.015
Central Florida Memphis 70.0% 0.010

I've been doing this for three years now, and the top three games on this list are the 1st, 2nd, and 4th most consequential games during that span.  So yeah, this is probably the best Championship weekend of the playoff era.  Three virtual play-in games, plus a really fun matchup in the Big 12 should make for a riveting day.

Weekly Playoff Probabilities - Week 12

As always, explanation here, ranking below, thoughts after.

Rank Team Agg Rank POFF Prob Change
1 Alabama 1 87.46% -0.8%
2 Miami (FL) 12 73.44% -2.4%
3 Wisconsin 7 60.15% 11.8%

15 Washington State 23 0.21% 0.0%

1.  The least consequential weekend of the year barely changed anything.  Wisconsin takes a small bite out of everyone else's odds after passing their biggest test thus far.  ND and UCF are still a bit too high, but they both fell just a bit.  Ohio State sits on the periphery still, which means they'll probably win the title.

2.  Just two teams leave us after the quietest weekend of the year: Michigan and Oklahoma State.  The Cowboys are the best team to leave the playoff chase, but they're still just 12th in the aggregate rankings.

3.  The conference-level stats remain familiar.  Both the SEC and ACC still have a decent chance of getting two teams in.  The Pac 12 is still dead.

SEC 1.357
ACC 1.290
B10 0.730
IND 0.259
AMER 0.183
B12 0.147
P12 0.034

4.  Four conference title matchups are completely decided, and all but one have at least one participant.  The MAC is the only conference where the final week will decide all.  And the Sun Belt is completely bananas.

Thanksgiving weekend will be one of the best of the year, thanks in large part to another formidable slate of home underdogs.  The Iron Bowl is the obvious highlight, but the true beauty of the weekend is that these 12 games take place in six different timeslots, so there's pretty much always something halfway decent on.  Enjoy.
