NFL Week Fourteen

 (Presented 100% free of Plaxico Burress jokes and commercial interruptions.)

1)  Predictions from last week

            We were 11-5 on Week Thirteen, making us 93-52-1 on the season.  The games on which we were wrong were Denver in New York against the Jets, San Francisco at Buffalo, Carolina at Green Bay, Atlanta at San Diego, and Kansas City at Oakland.   In all five cases we had predicted the home teams would win; in all five cases they lost.   But in all of those cases except one, we would have projected the game wrong even if the projected winners had been on the road.   The one case in which the home field advantage contributed to the wrong prediction was Atlanta at San Diego, which we had predicted as 25-23 San Diego.  It was actually 22-16 Atlanta. 

            Previous research (not by me) has shown that the home field advantage becomes larger in December, expanding from about three points to about five.   I thus have been wrestling with the question of whether I should expand the home field edge for the upcoming predictions, but I’m not going to do it.   The last two weeks, the home teams in the NFL have been 5-11 and 5-11.   Some home field advantage, huh?   I just can’t see projecting a larger home field advantage in that environment.

             Perhaps the most interesting thing is the re-emergence of Baltimore as an elite team.   I have sort of half-rooted for Baltimore for several years, ever since an Atlanta prosecutor filed bogus murder charges against Ray Lewis in a situation in which it could not possibly have been any more clear that Ray Lewis didn’t have anything to do with what had happened.   Lewis conducted himself throughout the ordeal with dignity, and it re-inforces my pro-Lewis attitudes when people carelessly insinuate that somehow he “got by” with something, when in reality the prosecutor should have been indicted for trying to frame him. 

            Anyway, Baltimore now has five dominating wins in the last seven weeks, despite having been on the road in five of the seven games—a 27-13 win at Miami, 29-10 against Oakland at home, 41-13 at Houston, 36-7 against Philadelphia and 34-3 at Cincinnati.    The other two games are a 37-27 win in Cleveland, and a 30-10 road loss to the Giants. 

            There are four teams in the NFL that have separated themselves from the pack, three of them in the AFC, and yet somehow Denver is going to sail into the playoffs with what amounts to a third-, fourth-place team, the eighth-worst team in football.   And, since they are in position to back off and coast into the playoffs, they may even win a couple in the post-season.   

 

4)  Team Scoring and Allowing Tendencies

            As you know if you have been reading these commentaries, I have been trying to develop a method to pin down the Scoring and Allowing Tendencies (S&A) of all the times.  .  .Trailblazer tells me that I still don’t have it, but beyond that I can’t figure out what he is trying to say.   I suspect that the method still needs some work. 

            Anyhoo, the method predicts that the number of points scored in a game will be the product of the S&A tendencies of the two teams.   This week Houston is at Green Bay.  Since the S&A numbers are 7.37 (Houston) and 7.83 (Green Bay), the method predicts that 58 points will be scored in the game—7.37 times 7.83.  Washington is at Baltimore.   Since the S&A numbers there are 5.37 (Washington) and 6.01 (Baltimore), the system anticipates that only 32 points will be scored in that game—5.37 times 6.01. 

            These are the current S&A numbers for the 32 NFL teams:

             Week 13 was a low-scoring week in the NFL, and most of the games wound up with fewer points than we had predicted.    Last week there were three games that we predicted would see more than 50 points, and two of them actually did.   But the third game, San Francisco at Buffalo, was the week’s lowest-scoring game, 10-3, so the average for the games that should have been in the fifties was only 44.0.   But that was still higher than averages for the games that should have been in the forties or the thirties:

           This week six games figure to be in the 50s, six in the thirties, and only four in the forties, although the norm, as we know, is in the 40s.

             Since all of the teams have played twelve games now, I thought I would look at how teams had played in the first six games vs. the second six.   Baltimore, the Jets, the Giants and, believe it or not, Kansas City have been the most improved teams in the NFL:

             Of course, Kansas City has been one of the most improved teams, Chicago has been the most disappointing team, but the Bears are still playing better than the Chiefs.   Everything is relative.   Thirteen teams have been better than average (>100) in both halves of the season, eleven have been worse than average in both halves, and eight have crossed the line one way or the other.  

  

Hum Baby

            Five NFL teams had their best weeks of the season in Week 13, while three had their worst.   Philadelphia, Denver, Tennessee, Pittsburgh and San Francisco had their best games of the year, by our system.     Arizona, the Jets and the Lions had their worst.

I also looked at the thing on Wikipedia.. . .which I find to be generally much more reliable than, say, academic research or conventional journalism. . .but there are a couple of things about the Ray Lewis entry that are a little amiss. One thing you didn't mention about the Wikipedia entry is that it pretty clearly blames the dead guys for starting the trouble. One problem with the entry is that the entry portrays the fight as starting outside the club, as the club was closing, whereas in reality the fight started inside the club. But Lewis did lie to police, and did try to cover up to keep his posse out of the investigation; I don't mind people pointing that out. But when he did those things, he had no way of knowing that the victims had died. He simply thought there was a fight, and he told the police he didn't know anything about it--not knowing that it was a homicide.

Figuring Wikipedia is always a good place to start if often a poor place to finish, I (finally) looked up what they had to say.

Current wisdom: Ray tried to be a peacemaker (obviously failed), did lie to law authorities in claiming to not know 2 suspects whom he did know, and as a 'deep pockets' guy paid out some damages to the families of the 2 people knifed (not shot, as I first 'recollected').

As to where on the Slime Ball-o-Meter a very hardball prosecutor should register, I'll choose somewhere above 'being shot'. But I've never been a prosecutor or prosecutee (discounting unknowingly driving with my headlights not-quite-turned-on). So feel free to discount this. Or even 'inappropriatize' it if you like.

C'mon, Bill. Your righteous anger is going to kill all the laughs my friends get when we watch the hometown team play defense and Ray Lewis makes a play, forcing the announcers to say something like "Watch the way he knifes through the defense." I'm really waiting for the Hall of Fame speech where his introduction references that he was "so fast, he could avoid Georgian authorities for 3 days."

Your half-recollection on Lewis is dead wrong, a, and b, any prosecutor who charged an innocent person with murder in order to pressure him to testify shouldn't be arrested; he should be shot where he stands.

Clark, the scores you cite pretty much meet my expectations about your and BillJ's computations. I'd expect you'd match BillJ's spreads almost exactly, and your total points should be lower than Bill's for AFC West and NFC South games and higher than his for AFC Central and NFC East games. (BTW, being different by 6 and 4 total points is pretty high for this point in the season, although 1 or 2 points each game could be round-off differences.)

Trailbzr, I assume your point is that the difference between Oakland's and Pittsburgh's S&A numbers doesn't reflect the quality of the offenses they've faced. Anyway, my system, which has offense and defense rankings generated arithmetically, generates very similar predictions. The biggest differences from a point scoring standpoint that I have are that I have CAR-TB at 17-16 and PIT-DAL at 26-16. The rest of my predictions are even more similar.

Bill, the way the SA factors is supposed to work is this:
Baltimore's pts/game = Baltimore's SA x Baltimore_Opponents_Average_SA

Baltimore has played: PIT 5.48, CIN twice 5.75, CLE twice 5.74, HOU 7.37, IND 6.32, TEN 5.97, MIA 6.36, NYG 6.95, PHI 7.08 and OAK 5.45. So Baltimore's Opponent's Average SA is 6.16. If you multiply that by Baltimore's SA of 6.01, the product is 37.0.

In Baltimore's 12 games, there have actually been 482 points scored, which is 40.2 PPG. Why is the SA product (37.0) so different from the actual PPG (40.2)?

The reason is: Baltimore's SA as calculated above does not take the Opponent's Average SA into account. The NFL Average SA is 6.69 as of Week 13. It looks like you calculated Baltimore's SA from Baltimore's PPG (40.2) divided by 6.69, which is 6.01. IF (which I doubt) all the other SA factors were correct, Baltimore's SA should be 40.2 / 6.16 = 6.53.

The same is true of the whole NFL. Take any team's PPG. Divide that number by 6.69. The result is the SA factor as calculated above. Example:
NYGiants = (352+206) / 12 = 46.5
46.5 / 6.69 = 6.95
Arizona = (338+313) / 12 = 54.25
54.25 / 6.69 = 8.11

If two teams, A and B, both have SA of 7.00 through Week 13, and A's opponent's have an average SA of 7.00 and B's have an average SA of 6.00, should A's games have averaged 49 points and B's 42? Oakland and Pittsburgh have nearly identical SA (5.45 and 5.48) and their games have seen nearly identical total points (437 and 439). But Oakland is in the same division as high-scoring Denver, San Diego and Kansas City; while Pittsburgh's division includes low-scoring Baltimore, Cleveland and Cincinnati. Isn't Oakland probably doing more to depress scores than is Pittsburgh?

Does anyone else understand my point?

Do you have evidence lousy teams which nevertheless back into the playoffs with rest beforehand then do comparatively well? Or are you only theorizing?

I half-recall that the prosecutor charged Lewis to try to pressure him into speaking up as to which of his buds in the limo had opportunity to do the murder. And Lewis clammed up as to what he knew. Are you saying that there's no reason to think anyone in Lewis' limo did the shooting, or just that it's outrageous that Lewis was actually charged with a murder he certainly didn't contribute to?
