Similarity Scores for the 2009 teams, part III
This is the third installment in a series of posts looking at similar historical teams through six games. The first installment looked at teams with at least 3 wins among those who did not have a bye in the first six weeks. The second post looked at the teams with losing record who played six games through the first six weeks. This one finishes up with the twelve teams who played their sixth game last weekend.
I don't know that this is rocket science, but when a team gets off to a 6-0 start and sets a record for most points scored in the first six games of a season, they are going to compare favorably to some other really good teams that continued to be good. The Saints have the highest expected win total of any of the 32 teams in this study. The Cowboys have a large number of teams that went on huge winning streaks over the second half of the season in their group.
Overall, my playoff odds calculation turned out to be pretty reasonable. The sum of the odds for AFC teams equaled exactly 6.00 teams making the playoffs. The sum of the odds in the NFC teams was slightly high (6.20), but this is explained by so many bad teams playing their seventh game last week, so the "through six games" record is slightly over .500. Also, I'm not taking into account that the NFC has several teams logjammed at 4-2 right now, so it's going to take slightly more wins than average to make the NFC Playoffs. So feel free to tick off a percent or two for the NFC teams and their playoff odds.
Teams are listed in descending order of playoff chances.

I think that the Cardinals playoff chances are slightly low, considering that they play in the NFC West.
I have a tough time judging the Cardinals season chances. I wouldn't be terribly surprised if they went 12-4, and I wouldn't be surprised if they went 8-8. Their schedule is fairly easy, but...
If they go 10-6, I think they win the division outright. If they only hit 9-7, I think SF has a chance. It'll be closer if SF manages to beat the easier teams and pull out a win against IND, PHI, or GB.
adjusting for strength of schedule so far and strength of schedule coming up, i have the cardinals winning a total of 12.2 on average and san fran winning a total of 9.1 on average.
I thought this was a little high, but i retested it through my method 3 times to make sure (i would gladly submitt my method if i knew the way). Interesting that the 1985 raiders, who won 12, are so high on the cardinal's similarity score.
Well the Niners didn't beat the Colts but they gave them a pretty good run for their money. Manning had 347 yards but 0 TD passes and was sacked 3 times, and had to come back in the 4th quarter. And Crabtree had 6 receptions for 81 yards in his second NFL game.
Makes me feel a little better about the 49ers chances. Even though their record is looking like previous years, it feels like they're more competitive against better teams. Now if the Panthers can just beat the Cardinals...
