I didn't get to post my final power rankings, but I did work up the regular season mathematical rankings, based on esoteric formulas that I have long since forgotten. I punch some numbers into Excel, it spits out rankings.
Interestingly enough, I would have personally picked all road teams last week, but the math rankings picked all the winners.
The Wild Card RoundIn the Falcons @ Cards, I thought the Cards really were the worst playoff team. Who knew they had a running game? Or a defense? In the overall rankings, the Cards were given a slight edge:
Cards: 12.8299 (16th overall)
Falcons: 10.4595 (19)
Winner: Cards (+2.3704)
What I think the overall numbers show is maybe a confidence factor. That game certainly could have gone either way, and a smallish differential shows low confidence.
Breaking out how the defensive versus offensive units matched up omits the special teams, but gives a very interesting set of numbers as well. It's all sort of an alchemy, but here goes.
Cards O: 34.8600 (4)
Falcons D: -26.6067 (24)
Winner: Cards (+61.4667)
It really did look like the Cards were running roughshod, on the ground and through the air, over the Falcons.
Falcons O: 31.1600 (7)
Cards D: -14.0641 (18)
Winner: Falcons (+45.2241)
Neither defense is very good, despite the heady strip and fumble return for a TD by the Cards, and good play in particular from Dockett. Both offenses were able to get points on the board, though, as the 30-24 score attests.
Deriving the difference of those individual offense v. defense matchups gives the 16.2426 edge to the Cards.
For the Colts-Chargers:
Colts: 20.5970 (14)
Chargers: 51.3953 (6)
Winner: Chargers (+30.7983)
Despite the hype, were the Colts really only the 14th best team in the league? And are the Chargers, despite a so-so record, as good as 6th?
Chargers O: 60.8600 (1)
Colts D: -15.7091 (20)
Winner: Chargers (+76.5691)
Colts O: 41.9600 (3)
Chargers D: -12.0080 (17)
Winner: Colts (+53.9680)
Delta: Chargers (+22.6011)
Which shows us the obvious: offenses ruled this game against not-so-great defenses. Steelers fans would be wise to note that the Chargers have that #1 offensive ranking, but their 17th ranked defense may help us get some points on the board.
Ravens-Fins:
Ravens: 87.4427 (2)
Fins: 26.7004 (11)
Winner: Ravens (+60.7423)
Fins actually ranked higher than the Colts overall, but the Ravens get a huge vote of confidence.
Ravens O: 4.8600 (14)
Fins D: 5.4694 (12)
Winner: Fins (+0.6094)
Fins O: 32.5600 (5)
Ravens D: 83.1922 (2)
Winner: Ravens (+50.0228)
Delta: Ravens (+50.0228)
So basically, the Fins D was about the equal of the Ravens offense in theory, but the Ravens D was not to be stopped here. Tell us something we didn't already know...
Eagles-Vikes:
Eagles: 86.5235 (3)
Vikes: 53.2749 (5)
Winner: Eagles (+33.2486)
Vikes actually got some respect from the math model, ranking 5th overall. Eagles show a very strong 3rd overall.
Eagles O: 3.2600 (15)
Vikes D: 76.4069 (4)
Winner: Vikes (+73.1469)
Vikes O: -8.4400 (22)
Eagles D: 80.9304 (3)
Winner: Eagles (+89.3704)
Delta: Eagles (+16.2236)
Take away that Westbrook run, and the story here really was the Eagles D doing its job just slightly better than that Vikes D.
Any Significance?I've been looking for a good score prediction formula for some time, but it never seemed to materialize. In breaking down the defense v. offense numbers, there did seem to be some correlation between the Delta number and margin of victory. I divided the Delta by the margin and averaged them out (2.707, 3.767, 2.779, 2.208; average = 2.82).
No idea whether that average will be a good predictor moving forward, but let's see. Using the math model to predict from here out gives some more perhaps surprising upsets...
Divisional PlayoffsCards-Panthers:
Cards: 12.8299 (16)
Panthers: 31.7306 (9)
Winner: Panthers (+18.9007)
Cards O: 34.8600 (4)
Panthers D: 0.9458 (14)
Winner: Cards (+33.9142)
Panthers O: 26.5600 (10)
Cards D: -14.0641 (18)
Delta: Panthers (+6.7100)
Margin: by 2 (rounded off)
A much closer game than I think most would expect. With offenses dominating the defenses, this should also be one of the higher-scoring games this weekend. So let's just call it 30-28.
Ravens-Titans:
Ravens: 87.4427 (2)
Titans: 56.1875 (4)
Winner: Ravens (+31.2552)
Ravens O: 4.8600 (14)
Titans D: 62.4250 (5)
Winner: Titans (+57.5650)
Titans O: -7.9400 (21)
Ravens D: 83.1922 (2)
Winner: Ravens (+91.1322)
Delta: Ravens (+33.5672)
Margin: Ravens by 12
Although this is pretty confident of a Ravens win, the defenses rule here (duh). Last time this game went 13-10; let's call it 22-10 this time around, with fortunes flipped.
Eagles-Giants:
Eagles: 86.5235 (2)
Giants: 48.4458 (7)
Winner: Eagles (+38.0777)
Eagles O: 3.2600 (15)
Giants D: 18.0120 (9)
Winner: Giants (+14.7520)
Giants O: 27.2600 (

Eagles D: 80.9304 (2)
Winner: Eagles (+53.6704)
Delta: Eagles (+38.9185)
Margin: Eagles by 14
Looks like the Eagles will try to repeat their win in Jersey again... Two TDs seems rather high, but I'll call this one 24-10 Iggles.
Steelers-Chargers:
Steelers: 94.5034 (1)
Chargers: 51.3953 (5)
Winner: Steelers (+43.1081)
Steelers O: 0.2600 (17)
Chargers D: -12.0080 (17)
Winner: Steelers (+12.2680)
Chargers O: 60.8600 (1)
Steelers D: 97.5853 (1)
Winner: Steelers (+38.7253)
Delta: 48.9933
Margin: Steelers by 17
Wow. Just look at the parity: #1 O vs. #1 D; #17 O vs. #17 D. This would seem to indicate that in the rematch, the Steelers don't just move the ball between the 20s. Low, low score last time, but this time it looks like the Steelers should control both sides of the ball, if just barely getting some life out of that fucknut Arians's offense. So let's call this one 30-13.
Conference PlayoffsPanthers-Eagles:
OK, I won't re-type all the offense, defense and overall numbers, just give the winners and margins.
Vote of confidence winner: Eagles (+54.7929)
Eagles O over Panthers D: +2.3142
Eagles D over Panthers O: +54.3704
Delta: Eagles +56.6846
Margin: Eagles by 20
Complete domination by the Birds. Let's call this Eagles 27, Panthers 7.
Steelers-Ravens:
Vote of confidence winner: Steelers (+7.0607)
Steelers D over Ravens O: +92.7253
Ravens D over Steelers O: +82.9322
Delta: Steelers +9.7931
Margin: Steelers by 3
Another ugly win. So let's say this is a 9-6 kinda game.
Super BowlSteelers-Eagles:
Vote of confidence winner: Steelers +7.9799
Eagles D over Steelers O: +80.6704
Steelers D over Eagles O: +94.3253
Delta: Steelers +13.6549
Margin: Steelers by 5
Another squeaker for the Steelers, and many fans might not enjoy a rather defensive scrum... but that's why Steelers fans will love this game. Could be four Jeff Reed field goals beating a Westbrook TD here... 12-7 Steelers?
OK. We'll see.
One game at a time...
