1.  This week's standings are as I would expect but for one glaring exception: NC State barely falling after getting pummeled by Clemson.  While I don't think they actually have a 13% chance of making the Playoff, it is at least reasonable upon further examination.  First (and most importantly), their remaining schedule is easy, which gives them a 20% chance of winning out.  This figure is far better than that of most one loss teams, including teams beneath them in the standings such as Florida (3%), Iowa (5%), West Virginia (2%), and Texas (2%).  Second, the carnage of the past several weeks has left a bit of a vacuum at the top, which means that teams with a high probability of finishing with one loss will fill in the void (The Wolfpack's context-free playoff odds are 7% but my adjustment moves them up).  Finally, they're really unlikely to have to play in the ACC title game now.  This actually helps them because 1) they would be a coin flip to take another loss in the game, and 2) being that the Coastal is garbage, it doesn't actually hurt their SOS to not play the game.

2.  Five more teams were eliminated this week as Mississippi State, Cincinnati, USC, Maryland, and Michigan State all lost their first and/or third games.  The Bulldogs are still 15th in the aggregate computer ratings (on account of their defense), while Michigan State and USC were both in the top 20 of my initial playoff odds.  This is all to say that this season is starting to get real.

3.  The ACC cannot be killed, the Big Ten takes a hit, while the Big 12 and Pac 12 make modest gains.  Still nothing much to see here.

Conference Exp Playoff Teams
SEC 1.428
ACC 1.043
IND 0.574
B10 0.500
B12 0.358
P12 0.087
AMER 0.010

4.  On the other hand, there's a bunch of fun stuff in the conference title grid.  Michigan is the new favorite in the Big Ten.  UAB has the second best odds of making a title game.  And there's a couple of super-wide-open divisions described in more detail below.

Conference Favorite Perc   Runner-Up Perc
ACCA Clemson 98.1%   Boston College 0.9%
ACCC Virginia Tech 42.2%   Miami (FL) 29.3%
AMEE Central Florida 66.1%   Temple 18.3%
AMEW Houston 87.4%   Memphis 5.6%
B10E Michigan 64.6%   Ohio State 33.8%
B10W Wisconsin 37.7%   Iowa 31.4%
B12 Oklahoma 75.7%   Texas 63.5%
CUSAE Florida International 44.6%   Marshall 35.1%
CUSAW UAB 90.4%   Louisiana Tech 4.8%
MACE Buffalo 77.0%   Miami (OH) 12.9%
MACW Western Michigan 56.2%   Northern Illinois 39.8%
MWCW Fresno State 88.2%   San Diego State 11.2%
MWCM Utah State 72.1%   Boise State 27.8%
P12N Washington 62.8%   Washington State 18.2%
P12S Utah 54.0%   USC 32.9%
SECE Georgia 57.3%   Florida 25.6%
SECW Alabama 89.7%   LSU 9.7%
SUNE Appalachian State 75.9%   Georgia Southern 12.8%
SUNW Arkansas State 61.0%   Louisiana-Lafayette 24.4%

4b.  First, let's check on the Big Ten West, which is officially in a four-way free-for-all.  And it's actually because the teams are all good!  Wisconsin has a tie-breaker over Iowa, but has to go on the road to Penn State, Northwestern, and Purdue over the next four weeks.  Purdue lost a tie-breaker to Northwestern way back in August, but their schedule is favorable the rest of the way.

Team Division Odds
Wisconsin 37.7%
Iowa 31.4%
Purdue 18.0%
Northwestern 12.9%

4c.  Next up is the American East, where undefeated South Florida has the fourth best odds of winning.  This is pretty simple to explain as 1) they still have to play the other three teams, and 2) they're not that good.

Team Division Odds
Central Florida 66.1%
Temple 18.3%
Cincinnati 10.0%
South Florida 5.6%

4d.  And finally, we have the Pac 12 South, which is drunk.  Utah is clearly the best team, but their difficult cross-division schedule has already saddled them with losses to both Washington schools.  As a result, everyone still has a chance, however faint. And yes, that includes a UCLA team that began the season 0-5.  Fun!

Team Division Odds
Utah 54.0%
USC 32.9%
Colorado 8.9%
UCLA 2.1%
Arizona State 1.7%
Arizona 0.3%

Another October week with minimal depth and one big game, but there's still enough to keep you interested.  The midday section has both the Cocktail Party and the weirdly good PSU-Iowa rivalry, but all three timeslots have something going on.  The weekdays are nice as well, with App State-Georgia Southern on Thursday and Miami-BC on Friday.
