AER2007 - Week 4

AIKMAN COMMENTARY – Week 4

There’s no surprise at the top of the Offensive Aikman Efficiency Ratings through four weeks of the NFL season with the Patriots, Cowboys and Colts sitting 1-2-3. In a slightly different order, these three teams also sit atop the NFL’s rankings which are determined only by total yards.

A huge gap of 11.4 ratings points has already emerged between the top three teams and Arizona which now sits in fourth in a cluster of four teams between 85.7 and 84.6.

The Cardinals’ jump from 22nd in the final 2006 AER Offensive Ratings (at 72.4) can be attributed in large part to the team’s success in the Red Zone in ’07. Arizona has reached the end zone on six of eight trips inside the 20 and has a hearty average of 6.00 points per Red Zone opportunity – second-best in the NFL at the moment.

- - -

Things can change quickly in the NFL – and the Raiders and Rams offer two cases in point.

The Raiders finished dead last in the 2006 NFL with their 54.6 Offensive AER. In fact, it was the worst Season Offensive AER we have recorded in our database that goes back to 1995.

That’s all changed in ’07 under Coach Lane Kiffin and with a re-emphasis on the running game. The Raiders are fifth in the Offensive AERs at the moment (and up to 10th in the NFL). The Browns, 30th in ’06, are also showing a major improvement as they now stand seventh in ’07.

On the other hand, the Rams had a fine offense in 2006. They finished the year fourth in the ’06 Offensive AERs at 84.4 for the season after blistering a 97.9 mark in the season’s final four weeks. But so far in ’07, they are dead last at 55.5.

- - -

Things are much more closely bunched on defense this year with the Eagles moving to the forefront after Week 4 – but seven other teams are within their 85.9 rating.

In that top group of eight, two teams that are significantly outperforming their NFL yards allowed ranking are the Vikings and Seahawks. Minnesota gets high marks for its rush defense, turnovers created and limited number of points allowed. In addition to turnovers and points, the Seahawks are getting extra points for limiting the number of first downs allowed.

- - -

The AER Game Ratings went 13-1 last week (the team with the higher AER Game Rating won all but the Packers-Vikings game) to go to 53-9 or 85.5% on the year.

Teams that have gained more yards have gone 43-19 for a 69.4% correlation to victory.

We cite this periodically as proof of our contention that the AERs provide a better indicator of the factors that actually win football games than just the matter of which team gained the most yards.

They're completely objective. What he thinks has no effect.

I think that's probably because they've given up TDs on 100% of their opponents' red zone appearances. The problem with weighting that stat too much (as I think Aikman does) is that their opponents don't get into the red zone very often.

It's like the LSU Tigers. Their opponents score a TD every time they get into the redzone. But their opponents are averaging 6.4 points per game.

Yeah, he can't subtract rating points for Jacques Reeves' phantom "pass interference."

Whether he hates or loves the cowboys is irrelevant as his effiency ratings are done with a mathematical formula, not with love and tender kisses.

Stinginess between the 20's has to be correlated to the weights in his formula, obviously. Or do you have access to how he's actually weighting red zone defense?

I'm surprised to see such a clear Dallas advantage in the combined rankings.

the 4 teams we've beat and the 1 we're about to play (buffalo) are all at the bottom of the combined efficiency ratings......

Maybe we could put in a request for love and tender kisses next time.

I'm not sure how he weighted them (or if he weighted it at all), but whenever Aikman talks about it, he talks constantly about redzone offense and defense.

Considering that 25% of those 4 teams' games have been against us, that makes sense.

That will all get worked out over the entire season. The Eagles are rated pretty high even though they are just 1-3 right now. I like Troy's system. It may not be perfect, but it is better than just using yardage like the NFL does. It provides a broader statistical picture that tends to match what I see when I watch these teams play. I don't see Denver as a top team even though they are rated highly based solely on yardage on offense and defense. In Troy's system they are middle of the pack.

Someone mentioned it is not a subjective system. It isn't in that it is not based on Aikman's opinion of any team. It is subjective in that he chooses which statistical categories to use and how much to weigh those stats. Subjective use of objective data or something. Someone else like Sagrin could use different stats and end up with a slightly different rating system.

Hmmm,

The Average of Offensive is 77 High is 101.3 low is 55.5.
The Average of Defense is 73.0 High is 85.9 low is 54.4.

Seems like there is a bit of a bias on the offensive side, since the range is much wider with a much Higher high. Also the average is slightly higher. So in the combined total rating, teams with a better offence would inherantly rank better than a team with a better defense.

Not saying this is wrong, but I wonder if it is on purpose, or just an abberation with this years stats. There have certainly been some dominating offensive teams this year...Cowboys included which is pretty freaking exciting given our recent history.

Probably is just the result of small sample size.

If you look at this post linked to below, you can see the highest rated offense and defense for every year since 1995. There does seem to be a slight bias towards offense, but it's not as pronounced as it is currently. But this could be a result of the rule changes over the past decade that have tipped favor toward passing games.

How long until the NFL's passer ratings are renamed the "Romo Efficiency Ratings"?

No kidding. At this rate, they'll have to rename a lot of awards and rankings after Tony.

That's it. The Lombardi could be renamed a "Tony". :laugh2:
