Why The 2015 Cowboys Defense Was Not As Bad As You're Being Told
http://www.bloggingtheboys.com/2016...oys-defense-was-not-as-bad-as-youve-been-told



For months, the nattering nabobs of negativism have been wallowing in the ineptitude of the 2015 defense and have been throwing around a few key stats to prove their point:

Just 31 sacks (ranked 26th)
Only eight interceptions (ranked 31st)
A meager three fumble recoveries (32nd in the league)

The best thing about those numbers is that they can be used to endlessly rain on the 2016 Cowboys parade! How can a team that's missing two of its best edge rushers for four games even dream of getting more than 31 sacks? How can a team that's returning stone-hands Carr and draft-bust Claiborne get any interceptions at all? And with no middle linebacker, forget about those fumble recoveries as well. In fact, forget about the entire dumpster fire that's the woefully under-manned, under-talented and over-self-medicated Cowboys defense.

Fortunately, not everything is that black and white, even if some would have you believe that. So it was with great delight that I re-read an article by Tom Cowlishaw of the Dallas Morning News from a couple of years ago, which explained what stats Rod Marinelli uses to assess his defense. Turns out, the Cowboys use a much more holistic approach to evaluate their defense:

When I talked to Rod Marinelli in training camp, he said there were only two sets of numbers he cared about for his defense: the Aikman ratings and turnovers.

The Aikman Efficiency Ratings were devised by - you guessed it - Troy Aikman, who was looking for a better way to rate offenses than the NFL’s "official" method of measuring offensive and defensive performance: yards gained or allowed. In 2006, together with Rick Odioso, a statistician for Fox Sports and Jim Henzler, a senior analyst for Stats Inc., Aikman created the formula for the Aikman Efficiency Rating (AER), which combines seven stats in five categories that Aikman and his cohorts believed offered a truer picture of offensive and defensive strength.

The exact formula used to arrive at the ratings was never made public, and remains proprietary to Stats Inc., but we do know what the seven stats are that go into the metric and how they are weighted in the metric:...

But before we walk through the individual stats above for the 2015 defense, let's first look at how the 2015 defense compared to the 2014 defense in its overall ranking:

Dallas Cowboys-2014 Defense/2015 Defense
Aikman Efficiency Rating
-69.6/67.0
NFL Rank-15th/17th


Going by the numbers here it's pretty clear that the 2015 Cowboys defense was just as good (or bad) as the 2014 defense. You've ben told otherwise, you may even believe otherwise, but the metric the Cowboys use to evaluate their defense speaks a clear language.

Compare that to the numbers for the Cowboys offense and the difference is much clearer.

Dallas Cowboys- 2014 Offense/ 2015 Offense
Aikman Efficiency Rating
-90.9/73.7
NFL Rank-3rd/29th


The Cowboys offense, provided its key players stay healthy, is widely expected to bounce back to somewhere close to the level it played at in 2014.

It turns out, while the Cowboys 2015 was deficient in turnovers and sacks and many other categories people point to when they rate a defense, they were average in the most-important stat, points allowed, and they were actually among the better teams in one category, redzone defense.

The Dallas defense was 25th in defensive DVOA on the first 80 yards of the field, but the Cowboys improved to seventh inside the red zone.

First down achievement.

  • The Cowboys allowed 317 first downs last year, the 14th best value in the league and a slight improvement over their 17th rank from the year before
  • Last year, they were ranked 15th with a 38.9% third down conversion percentage allowed, a significant improvement over their 43.6% percentage from 2014 (27th).
Turnovers: As already mentioned, the Cowboys fell from second overall with 31 takeaways in 2014 to dead last in the league with 8 takeaways.

This isn't to say we wouldn't like to see improvement on the Cowboys defense, the lack of sacks and pressure on opposing quarterbacks is an unsettling trend. But, to say the Cowboys can't be a serious contender because of their defense overlooks the fact that a similar defense in 2014 was plenty good enough to keep the Cowboys in the hunt. What they benefited from was a powerhouse offense that controlled the clock, kept pressure on opposing offenses that in turn led to turnover opportunities

So when you hear the Cowboys can't contend with their current defense, don't believe it. Sure it would be easier if their defense was stronger, but you play with what you have. Plenty of teams would love to have the Cowboys offense, trade offs in the NFL are a fact of life. As long as the defense remains stingy in the redzone, the offense can take care of the rest.

2013, 14, and 15 all were terrible defenses.

2016 looks to be just as bad.


The problem with these Mike Zimmer and Marinelli schemes is that it's almost impossible to get off the field in critical moments of the game.

When you have no pass rush like we do you can't just send 4 and rely on coverage.

According to the MET ( my eyeball test) the 2014 and 2015 defense where not that good.
2016 doesn't seem to be much better. Hopefully the offense will cary us to the playoffs. Give Romo a Denver like defense and we are Super Bowl champs!

Rebuilding almost entirely through the draft takes a while. This season and the next they could make significant strides forward if Lawrence, Gregory, Tapper, Collins, Smith, Jones, Irving, Russell, and Mayowa pan out,,, I think they will. Maybe even Claiborne.

We were 16th in points and yards last year. That is average not terrible else anything not top 10 is terrible.

Cowboys were better in almost EVERY area in 2015 than they were in 2014. Takeaways was the only place that the 2014 D was head and shoulders better. So Cowboys expect similar results in 2016 to 2015 PLUS increased turnovers like in 2014?

That is surprising conclusion considering the Cowboys are losing TWO key players in 2016: Greg Hardy and Ro McClain (paired with Sean Lee). And none of the new additions have proven the ability to replace that production. Not to mention Lawrence and Gregory will be out 4 games, at least. Thornton is an upgrade to Hayden, no argument there. But Hitchens is no Ro McClain. And more importantly, Mayowa/Tapper/fill in the blank will not create one on ones for their teammates like Hardy did.

Wish Cowboys youngsters will step up big too, but wishing is not a solution, it is a step back. Cowboys will be lucky to generate 2015 numbers, sans the turnovers.

You really want us to believe that the entire franchise has been sitting on their collective laurels in the development of the defensive side of ball? I sure don't...and things will be much more in balance than last season. That is plain...and simple.

Sitting on defensive laurels? Great phrase but very amusing. What laurels has the D earned since Wade's departure?
