• Minnesota's zone-heavy defense collapsed to the Cowboys in Week 11 (0.7 EPA/play in zone). Fortunately on Thanksgiving, Minnesota now hosts the Patriots, who have NFL's third-lowest EPA vs zone.

• After brief week away, the Chiefs again top the league in most man coverage faced (41.6%).

• We'll see ultimately Sunday how much power the Chiefs have on the opposing defense’s gameplan when they take on the Rams, who run league-high 90% zone.

Whether to run man coverage or zone coverage is a big decision for each NFL team, and many factors influence their decisions during and in preparation for the game, including the talent level of the defense itself and the talent level of the offense they will be facing. Some teams’ schemes work better with man coverage, while others work better with zone, and PFF’s Arjun Menon and Judah Fortgang analyzed this in a previous article titled “Should NFL teams be playing more man or zone coverage?”

Each week, we will detail how teams varied in the use of man and zone coverage, and how it may have differed from their previous week. As we get more data, we will eventually make predictions for each team’s man and zone coverage rates for the next week, and analyze those predictions.

This Week’s Man and Zone Rates

Playing man and zone coverage could depend on the strengths and weaknesses of the opponent the team faces. In Week 11, the league as a whole ran man coverage 30.1% of the time, down slightly from 30.6% last week. Highlighted in this week’s Coverage Update article, here are the teams that ran the most man and zone coverage in Week 11:

Top 3 in Man Coverage rate in Week 11

Pittsburgh Steelers (61.9%)

New York Giants (61.3%)

Los Angeles Chargers (56.1%)

Top 3 in Zone Coverage rate in Week 11

Baltimore Ravens (92.9%)

Chicago Bears (91.7%)

Atlanta Falcons (88.2%)

Note: From 2019-2021, the league average for running man coverage was 33.9%, and zone was 66.1%.

The Pittsburgh Steelers and New York Giants both chose to run more than 60% man coverage in their games against the Cincinnati Bengals and Detroit Lions, respectively. They are regularly some of the most man-heavy defenses, along with the Lions. However, the Giants’ man coverage was much more effective than the Lions’ in their game in terms of EPA, but Detroit was able to get the win.

The Baltimore Ravens ran the most zone coverage in Week 11 against the Carolina Panthers, and it was highly successful, as they held Carolina to -0.45 EPA per play while facing zone. The Panthers’ offense has faced mostly zone this season and has struggled to move the ball, so the Ravens continued the trend.

Evolving Defensive Man and Zone Rates

Some teams’ man and zone rates will vary by opponent, while some will stay steady throughout the season. So far, the league as a whole ran man coverage 29% of the time, therefore running zone on 71% of plays. From 2019-2021, the average man coverage percent was 33.9%, so the league is running about 5% more zone coverage this season. Below, we can see how each team’s percentage of running man and zone coverage evolves each week.

We’ve talked about how the Los Angeles Rams defense doesn’t vary their man and zone coverage rates (as they’ve stuck to running around 90% zone coverage in every game), but we haven’t dived deep into the Vikings here yet. The Minnesota Vikings have had the same coverage gameplan as the Rams, except they’ve been winning games. After their collapse against the Dallas Cowboys (allowing 0.7 EPA per play in zone), it might be time to wonder if they’ll try running some more man coverage to see if that works.

The Chicago Bears‘ man and zone coverage rates have been all over the place this season. They’ve tried just about every combination, but none have been successful (allowing over 0.15 EPA per play with both). Like the Texans, their lack of defensive success is becoming more about their poor play than the weekly scheme.

After poorly running a ginormous amount of man coverage last week, Dan Quinn went back to his normal gameplan by having the Cowboys play much more zone coverage against the Vikings. It was ultimately a great bounce-back game for the Cowboys defense.

Man and Zone Rates Each Offense Faced

Teams often base their defensive coverage play calling based on the particular opponent they are facing. Let’s see how often each offense had faced man and zone coverage by the opposing defense, and how it’s differed by week.

Against the Philadelphia Eagles, the Indianapolis Colts’ coverage unit didn’t copy the Washington Commanders’ winning gameplan and instead ran man and zone each 50% of the time. However, this gave the Eagles the most trouble this season, as they averaged -0.18 EPA against man coverage and -0.29 EPA against zone. Aside from the 4th quarter, the Eagles were shut down, and are proving that they are not the unstoppable force they were in the beginning of the season.

The Bengals have faced more man coverage in their past 2 games, which could be an adjustment by opposing defenses given that Ja’Marr Chase continues to be out with a hip injury.

After a brief week in second, the Kansas City Chiefs once again top the list in terms of facing the most man coverage this season, courtesy of the Los Angeles Chargers running 56% man coverage against them this week. The Chiefs do have the highest EPA per play against zone (0.23), but their EPA per play against man is even higher (0.35), which is good for second in the league behind the Miami Dolphins. It’s hard to understand how defenses are consistently underestimating the Chiefs’ pass catchers without Tyreek Hill.

Week 12 Predictions and Matchups to Watch

After the Vikings’ zone coverage completely collapsed last week against the Cowboys, will they attempt to run some man coverage against the Patriots on Thursday? The Patriots face an average of over 30% man coverage each week, a percent the Vikings haven’t come close to this season. However, the Patriots are the third worst offense against zone coverage in terms of EPA, so it wouldn’t be surprising if the Vikings stick to their regular gameplan.

This week, we will ultimately see how much power the Chiefs have on the opposing defense’s gameplan when they take on the Rams. The fact that the Rams refuse to change their coverage gameplan against any opponent by consistently running 90% zone coverage each game may actually be to their benefit this week. Could they be the first team to succeed? Or will they be led into the trap and run a high rate of man coverage against the Chiefs?

The New York Jets offense currently has the worst EPA per play against man coverage. In Week 12, they take on the Bears, who run an average amount of man coverage. Will the Bears opt for even more man coverage this week, and will new starting quarterback Mike White be able to turn the Jets’ offense around?
