1.  A weird weekend didn't change much for the contenders.  Georgia passed a test and jumped as a result - otherwise all we see are small adjustments.  The only other massive change comes from NC State losing, which means they're no longer messing up my model.  Good.

2.  The weekend was mostly kind to the top teams, but was absolutely brutal to two-loss power conference teams.  Washington, Texas A&M, Stanford, Miami (FL), Texas Tech, Wisconsin, Duke, Virginia Tech, Colorado, South Florida, and Oregon were all eliminated from the fringes of playoff contention.  Washington is the first legitimate contender to be eliminated, as they remain 8th in the aggregate ratings.  Also, a 10-2 Texas A&M would have been a fascinating test case for the committee, but unfortunately the Aggies weren't quite good enough in Jimbo Fisher's first year.

3.  Half the top ten is SEC teams, hence their dominance here.  Their chance of getting two teams in the playoff will likely go down next week, especially if Alabama wins at LSU.

ACC 0.994
IND 0.599
B10 0.468
B12 0.348
P12 0.091
AMER 0.009

4.  Utah, Virginia, and Northwestern all had amazing weeks, as they all won and all of their fellow divisional contenders lost.  The Big Ten West will likely come down to the Iowa-Northwestern winner, but Wisconsin and Purdue still have about an 8% chance each.  The Pac 12 North will almost certainly come down to the Apple Cup on Thanksgiving Friday.  West Virginia (40%) and Iowa State (23%) are still strong contenders for the Big 12 title game.  And Pitt is still at 9% to win the ACC Coastal because nothing matters anymore.  The Sun Belt is drunk.

The best weekend of the year has insane quality and depth.  Basically half the good teams go on the road as touchdown favorites.  Texas-West Virginia will determine the Sooners' main competition in the Big 12.  UCF-Temple will possibly decide the American.  And we get the most important Virginia-Pitt game ever on Friday night.

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

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%

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.
