2023 Cowboys analytics roundup: Dallas drops after crushing Bills’ loss

2023 Cowboys analytics roundup: Dallas drops after crushing Bills’ loss

How detrimental do you think last week’s game was for the Cowboys? Well, it was quite an event. The Cowboys faced a tough match in Buffalo, where they were dominated in every aspect of the game and ended up losing 31-10, leaving many Cowboys fans lacking confidence. Amidst all the chaos, it’s worth noting that Dallas secured a playoff spot just before the game started. However, their chances of hosting at least one playoff game diminished after the defeat.

Certainly, the Cowboys have secured a playoff spot, an achievement accomplished just one game into December. Yet, the question arises: how do they compare to the top teams, and to what extent did the disheartening loss to the Bills set them back? As usual, it’s that time of the week when we rely on analytics to delve into these matters.

Cowboys Efficiency at a Glance

DVOA DVOA Rank DVOA Rank Previous Rank Weighted DVOA Weighted DVOA Rank
Offense 9.4% 9th 6th 12.3% 7th
Defense -6.9% 6th 5th -4.5% 9th
Special Teams 2.7% 7th 8th 3.4% 6th
Overall 19.0% 6th 4th 20.2% 6th

Predictably, the Cowboys have experienced a decline in the DVOA rankings following their recent game, slipping from the fourth position to the sixth overall. Notably, there is a considerable gap between them and the two teams immediately ahead, one of which happens to be the Dolphins, the upcoming hosts for the Cowboys.

Nevertheless, the Cowboys maintain the second-best DVOA grade in the NFC, with the Lions trailing behind at the seventh spot with a significantly lower 14.2% grade. While there is a substantial difference between the 49ers and the Cowboys, there is also a notable separation between Dallas and the rest of the conference.

This trend is mirrored in the team tiers based on EPA, where the Cowboys exhibit a substantial lead over the Eagles and Lions, though there remains a notable gap with San Francisco. Overall, the Cowboys find themselves in a favorable position, yet the stark contrast between the top two NFC teams raises concerns about their playoff durability.

Interestingly, it is both intriguing and somewhat amusing that the Cowboys and the Dolphins share nearly identical total EPA/play in the week they face each other. Despite their divergent strategies and personnel, the team efficiency metrics suggest a closely contested match.

Offense

Cowboys Offensive Efficiency

Grade Rank
Offensive DVOA 9.4% 9th
Pass DVOA 23.9% 10th
Run DVOA -3.2% 13th
EPA/Play 0.114 4th
EPA/Dropback 0.204 2nd
EPA/Rush -0.037 9th

The Cowboys offense had a poor game, easily their worst since the Week 5 disaster against the 49ers. Some external variables contributed, but Buffalo also played exceptionally effectively on offense, regularly removing the first and second read as their pass rush went to work.

Having said that, the offense’s efficiency ranks did not decline significantly. To be sure, they fell overall, but not dramatically. This is still a top-10 offense by nearly every metric, and there’s reason to believe they’ll get back on track this week in a much better setting.

Dak Prescott’s Efficiency

Grade Rank
QBR 72.7 2nd
EPA/play 0.225 2nd
CPOE 3.3 7th
DVOA 18.2% 6th
DYAR 1023 5th

In his inaugural match as the clear frontrunner for the MVP award, Dak Prescott delivered a subpar performance. His player grade of 39.4 from Pro Football Focus marked his lowest of the season. Prescott struggled throughout, completing only 61.8% of his passes and committing four plays deemed worthy of turnovers, including an interception. This performance contrasted sharply with his previous eight games, where he had only three turnover-worthy plays and one interception.

However, similar to the overall offensive struggles, Prescott’s off-game doesn’t overshadow his exceptional season. Despite the setback, he continues to have one of the finest quarterback seasons this year, maintaining a top-four position in MVP odds according to most sportsbooks. Although Prescott faces a challenging path to re-enter the MVP race, his performance in the remaining three weeks will significantly influence the ongoing conversation about his candidacy.

Cowboys Offensive Line Efficiency

Grade Rank
Pressure Rate 15.0% 3rd
Adjusted Sack Rate 7.0% 13th
Blown Block Rate 2.44% 11th
Pass Block Win Rate 57% 18th
Run Block Win Rate 72% 5th
Adjusted Line Yards 4.33 8th

Surprisingly, despite Prescott being sacked three times, the Cowboys’ offensive line didn’t suffer significant setbacks in performance metrics this week. In fact, they were officially charged with only one sack and five pressures. This can be attributed to Prescott’s prolonged average time of 2.93 seconds per throw, an unusually high and unsustainable duration for any offense. This extended time to throw highlights how frequently the Bills disrupted Prescott’s initial reads, compelling him to move around more than usual.

Reinforcing this observation is the fact that the offensive line’s win rates, both in pass protection and the running game, remained consistent this week. These metrics gauge the line’s ability to maintain their blocks for 2.5 seconds, irrespective of the events that unfold beyond that timeframe. Although Prescott faced considerable pressure in the game, the offensive line generally upheld their responsibilities more often than not.

Defense

Cowboys Defensive Efficiency

Grade Rank
Defensive DVOA -6.9% 6th
Pass Defense DVOA -4.2% 6th
Run Defense DVOA -10.2% 16th
Pass Rush Win Rate 60% 1st
Run Stop Win Rate 29% 29th
EPA/Play -0.086 6th
EPA/Dropback Allowed -0.080 6th
EPA/Rush Allowed -0.097 13th

We’ve reached the defensive segment of the analytics roundup, where the critique intensifies this week. Describing the Cowboys’ defensive performance as putrid would be an understatement. Their run defense suffered a significant blow, getting exploited to a staggering extent. The impact was so substantial that they plummeted from sixth to 16th in run defense DVOA in just one week. Reflecting on this, consider the rarity of such a drastic shift.

DVOA grades are expressed as percentages, taking the entire dataset into account. Typically, with more data, DVOA grades exhibit less volatility from week to week. For the Cowboys to experience a 10-spot drop in a single week, despite 15 weeks of data contributing to the grade calculation, indicates a historically disastrous game of epic proportions for their run defense.

Cowboys Pass Coverage

letions Completion Rate Passer Rating Allowed ADOT When Targeted Air Yards Allowed Yards After Catch
Trevon Diggs 8 2 25.0% 1.0 15.9 6 20
Stephon Gilmore 74 40 54.1% 83.2 10.9 341 179
DaRon Bland 76 41 53.9% 49.9 11.6 346 189

Donovan Wilson 19 15 78.9% 129.8 4.8 36 92
Juanyeh Thomas 12 7 58.3% 98.3 3.3 5 52
Leighton Vander Esch 7 5 71.4% 87.2 0.4 -1 44
Markquese Bell 36 26 72.2% 90.2 1.1 4 237
Damone Clark 26 21 80.8% 102.7 1.4 7 138

Surprisingly, the pass defense displayed a satisfactory performance in this game. Admittedly, this can be attributed to the fact that Josh Allen threw only 15 passes throughout the entire game. Nevertheless, Dallas performed well when Allen did decide to throw. The absence of Malik Hooker raised concerns about the defense’s capability to prevent deep shots, a staple of the opposing offense. However, Allen attempted just one pass over 20 yards downfield, which unfortunately ended in an incomplete pass.

The only defensive player who encountered difficulties in coverage during this week was Damone Clark, although this observation is based on a limited set of instances. Clark’s singular target occurred in the red zone against James Cook, resulting in a touchdown for Cook. It’s challenging to draw significant conclusions about the secondary’s performance from this particular game, but the upcoming challenge against the Dolphins is likely to provide a more comprehensive test.
