week 7: 1.6%, 3.5%
week 8: 7%, 14%
week 9: 3.4%, 8%
week 12: zip
week 13: technically 2 out of 1000, in reality zip.

After week 7:
At these very preliminary stages, I estimate that the Chiefs chances of making the playoffs are only about 3.5%. This is lower than the estimate I posted in another thread earlier today because the website I down loaded the scores from had an error. I think the revised estimate is a little low for reasons that I will explain below. In many of the cases where they made it, they did so with a 9-7 record. Projected AFC division winners right now are New England, Pittsburgh, Jacksonville, and Denver*. Strongest additional contenders are the Jets, Indy, San Diego, Baltimore, Houston and Cleveland. As you can see, things are pretty crowded in the AFC.

In the NFC, projected division winners are Philly, Minnesota, Atlanta, and St. Louis. Also in the thick of the race are the Giants, Detroit, Seattle, Arizona, Green Bay, Dallas and nearly everyone else. The quality of teams in the NFC is much worse so far. My program is predicting that 8-8 or even 7-9 might be enough to win the NFC west or a wildcard.


The attached txt file contains the detailed breakdowns. For each team, the first number is the odds of winning the division, the second number is the odds of making the playoffs, and the third number is the power rating I used to calculate the outcome of the remaining games.

Overall, these predictions seem a little optimistic for the front-runners. This is always a problem early in the season, but is even more so this year because so far their have been relatively few games where a team of lower power rating beats a team of higher power rating. Tinlar pointed this out the other day in his power ratings. This leads my program to believe that the NFL is predictable with a high degree of accuracy and favors front-runners disproportionately. As we get a few more upsets, things will even out. Another way of handling this is to include uncertainty in the power ratings (Bayesian statistics), but that would require another revision of the program and a few hours of computer time to calculate.

Rep to cdcox for the asterisk.


Mods, is there any way we can replace the Denver Smiley with an asterisk and cdcox's footnote? That's be cool.

Again I say this, we must win out this year to get the division title.

Jax. and Indy both will go around 12-4, 11-5 with there schedules. The Jets are a lock with there schedule, unless either of these 3 teams does a complete fallout, we are out of the picture in the WC.

The Indy game is a must for 2 reasons, game up on WC and the fight to finish winning out !

After Week 8 (assuming the Jets hold on):

Kansas Cityís playoffs chances climbed to about 14% with the win over the Colts. Hope should be officially alive. Division favorites in the AFC are New England, Pittsburgh, Houston!, and San Diego! Other strong competitors include: the Jets, Denver*, Jacksonville, Baltimore, Indy, and KC.

In the NFC, division favorites are Philadelphia, Minnesota, Atlanta, and St. Louis. The strongest competitors among the remaining teams are the Giants, Detroit, Seattle, Green Bay and Dallas.

As it stands now, with Denver and SD tied at 5 wins ... and Denver having already defeated SD, how is it that SD is the AFCW favorite?

I like the work you do ... just curious.

Really,it's simple, all we need to do is win them all, the division is ours, Denver and SD will be taken care of as SD beating Denver.

Now the hard part of simple ... winning out !

Thanks for the question. These are useful because it requires me to check that things make sense, thereby identifying areas for improvement.

First of all, San Diego only has a slight edge over Denver* for the predicted division winner. 48.9% to 43.9%. You can see this in the detailed text. The difference comes down to the power ratings: San Diego has a slightly higher power rating, thus meaning that the computer predicts that it will win more games from here on out than Denver*. This has to do with the outcomes of the games so far:

San Diego:
Wins over: Houston, Tennessee, Jacksonville, Carolina, and Oakland. Losses to: Jets, Denver*, and Atlanta

Devner*:
Wins over: Kansas City, San Diego, Tampa, Carolina, and Oakland.
Losses to: Jacksonville, Cincinnatti, and Atlanta

San Diego has two wins against quality teams (Houston and Jacksonville) and all their losses were to quality teams. Denver* has two wins over quality teams (Kansas City and San Diego) but thier losses include one to a lower quality team (Cincinnatti). That is the difference in power rating, and thus the reason they are slightly favored to win the AFC west. Of course my program is completely wrong about this. KC will win the west.

After Week 9:

Kansas Cityís playoffs chances dropped by nearly half to an anemic 8% after losing to the Bucs. We still have a chance due to the influence of parity in the league. Only Pittsburg, New England, the Jets, and Baltimore are ranked significantly above KC in power ratings in the AFC. However, our sub par record hurts us, obviously. Division favorites in the AFC are New England, Pittsburgh, Indianapolis, and Denver*. Other strong competitors include: the Jets, San Diego, Jacksonville, Baltimore, and Houston.

In the NFC, division favorites are Philadelphia, Minnesota, Atlanta, and Seattle. The strongest competitors among the remaining teams are the Giants, St. Louis, Green Bay, Detroit, Tampa, and Dallas. I predict that at least 2 playoff qualifiers from the NFC will have records no better than 9-7.

It has been a while since I updated these for several reasons: 1) lack of interest because of the collapse of the Chiefs and 2) hoping to have enough time to implement draft pick order prediction. Anyway, with the interest in the Broncos crash and burn on the rise, I decided to do an update. I also want to document the predictive ability of the program over the course of a season. Without further ado...

After Week 12:

The Broncos chances of making the playoffs are 48%. Their chances of winning the division are 24%. AFC Division favorites are New England, Pittsburgh, Indianapolis, and SanDiego. Other strong competitors include: the Jets, Baltimore, Broncos, and Jacksonville.

NFC division favorites are Philadelphia, Minnesota, Atlanta, and Seattle. The race for the wildcard is wide open. Iím sticking with my prediction made in week 9 that at least 2 teams that qualify from the NFC will have records no better than 9-7. Could even see a 7-9 record make it. The strongest competitors among the remaining teams are the Green Bay, St. Louis, Giants, Arizona, Detroit, Carolina, Tampa, and Chicago,.

After Week 13:

Donk haters rejoice! The Broncos playoff chances have dropped to 37%. Iíd like to thank them for making playoff predictions fun again.

The AFC division leaders are New England, Pittsburgh, Indianapolis, and San Diego. All of these teams are more than 95% likely to win their divisions. The Jets have all but sewn up one wild card position. Leaders for the last position are the Ravens, Broncos and Jags.

The NFC is a joke. The division leaders are Philadelphia, Minnesota, Atlanta, and St. Louis. Philli and Atlanta have sewn up their divisions, but the other two races are wide open with even Chicago and Arizona having a shot at winning their divisions. Similarly the wild card race is wide open. The runner up in the NFC North (Minnesota and Green Bay) has the best shot. Only SF is out of contention for the Wild Card. Everyone else has odds of 4% or better.

After Week 15:

The Chiefs have dropped the Broncos* playoff chances to 22%. I canít tell you how happy it makes me to type that.

New England, Pittsburgh, Indianapolis, and San Diego have all clinched their divisions. I predicted this 3 weeks ago, but probably would have picked it up a week or two earlier had I run my program every week. The Jets have about a 98% chance of grabbing one wild card. The last position will probably go to the Jags (35%), Ravens(30%), Broncos* (22%), or Bills (15%).

In the NFC, Philadelphia, and Atlanta have clinched their divisions. I have predicted these since week 7 when I did the first predictions. The other two division races remain very competitive. Minnesota and Green Bay are about even favorites to win the division. Green Bay has sewn up at least a Wild Card and Minnesota is about 99.7% sure to make at least a wild card. Seattle has a 73.5% chance of taking the West. The race for the final wild card spot (assuming GB or Minn takes one) is still wide open; the leaders are: Carolina (44%), New Orleans (21%), Washington (9%), St. Louis (7%), Chicago (7%) or Seattle (6%).

No, that reads:

0, .002, 23

which parses as:

zero chance of winning the division, 2 chances in 1000 of making the playoffs, and power ranking of 23.

In other words, it ain't gonna happen this year.
