Wrapping up our look at returning players and new veterans on defense, today we’re going to explore stopping the run.
This can be difficult to quantify, because much of what goes into run stopping doesn’t get measured. When Eddie Goldman holds his own against two blockers, he frees up a linebacker to make the tackle, but nothing Goldman did there shows up on a stat sheet. So I want to be clear from the start that this is not going to be a perfect science, and I make no claims that it is.
However, Pro Football Focus (PFF) does track some data that can give us an idea of how often a defender is directly involved in stopping a run play. We’ll look at basic metrics that are fairly self-explanatory, like how often a player makes a run tackle or misses a tackle, but also some more advanced data including how far downfield the average run tackle they make is.
One unconventional stat PFF uses that I want to briefly discuss is a “run stop.” PFF defines this as a solo tackle that counts as a “win” for the defense. I can’t find anything definitively saying what makes a play a “win,” but you can imagine this is probably similar to success rate, where it keeps the offense from picking up a certain % of the yards needed for a 1st down. In other words: a defender made a tackle to keep the run short and force the offense behind the chains.
I will examine every Bears defender who had at least 200 run defense snaps last year, whether in Chicago or somewhere else. This allows for a large enough individual sample size that the values have some meaning, but also a large enough sample size for comparing players from a position to their peers. The 200 snap threshold gave a sample of 74 interior defensive linemen (2.3/team), 52 edge defenders (1.6/team), 66 linebackers (2.1/team), 75 cornerbacks (2.3/team), and 70 safeties (2.2/team). That adds up to 10.5 defenders/team, or roughly those who played starter-level snaps.
Let’s start with a look at the defensive line, where the Bears return Angelo Blackson and added Justin Jones in free agency. The table below shows how they both fared in a variety of run-stopping metrics last year, as well as their rank compared to 74 interior defensive linemen who played at least 200 run snaps. To give a broader frame of reference, the best, average, median, and worst values among that 74-player sample are also provided for each statistics. Categories highlighted in green indicated the player was in the top 25% relative to their peers, while red indicates the player was in the bottom 25%.
A few thoughts:
Let’s switch gears and examine the edge rushers now, where the Bears have three notable players: returnees Robert Quinn and Trevis Gipson and newly signed Al-Quadin Muhammad. The table below shows their performance against the run in a variety of metrics, including their rank compared to 52 positional peers.
Today we’ll switch to look at how linebackers and safeties have fared in coverage.
Like I did with cornerbacks, I’m using data from Pro Football Focus (PFF) that looks at how frequently and effectively individual players are targeted in coverage. I chose to set a threshold of 250 coverage snaps because it both gives a decent enough sample size to judge an individual player and gives a big enough grouping of players at each position to evaluate how somebody performed relative to their peers. This threshold gave a sample size of 68 linebackers (2.1/team) and 82 safeties (2.6/team).
Let’s start with a look at linebackers, where the Bears return Roquan Smith and bring in Nicholas Morrow. The table below shows how they fared in a variety of coverage metrics last year, as well as their rank compared to 68 linebackers who had at least 250 coverage snaps. To give a broader frame of reference, the best, average, median, and worst values among that 68-player sample are also provided for each statistic. Categories highlighted in green indicated the player was in the top 25% relative to their peers, while red indicates the player was in the bottom 25%.
Note: Since Morrow missed the 2021 season with an injury, his data is from 2020, but he is still ranked against his peers in 2021. I know this is not perfect, but these values shouldn’t change that much league-wide year over year, and it saved me a ton of work.
A few thoughts:
Today we’re going to shift from examining players who rush the passer to those who defend passes that are thrown. We’ll start by looking at the CBs, with an upcoming article to look at linebackers and safeties.
In order to do this, I’m using data from Pro Football Focus (PFF) that looks at how frequently and effectively individual players are targeted in coverage. I chose to set a threshold of 250 coverage snaps because it both gives a decent enough sample size to judge an individual player and gives a big enough grouping of players at each position to evaluate how somebody performed relative to their peers. This threshold gave a sample size of 106 cornerbacks, or 3.3 per NFL team.
The Bears have four notable veteran cornerbacks: returners Jaylon Johnson, Kindle Vildor, Duke Shelley, and newcomer Tavon Young. The table below shows how they fared in a variety of coverage metrics last year, as well as their rank compared to 106 cornerbacks who had at least 250 coverage snaps. To give a broader frame of reference, the best, average, median, and worst values among that 106-player sample are also provided for each statistic. Categories highlighted in green indicated the player was in the top 25% relative to their peers, while red indicates the player was in the bottom 25%.
A few thoughts:
Almost everything I’ve looked at so far this offseason has been about the offense, so now I want to shift gears and give some attention to returning players and new veterans on defense. That starts today with a closer examination of the pass rush.
In order to do this, I’m using data from Pro Football Focus (PFF) that examine pressures, wins, sacks, and pass rush productivity. Here’s a quick explainer of what PFF means by some of those that are less obvious:
I’ll examine both all pass rushing snaps and only what PFF defines as true pass sets. These are basically set up to only look at 4-man rushes on standard passing plays, so all screens, play action, designed rollouts, blitzes, 3-man rushes, and exceptionally fast (ball thrown in <2 seconds) or slow (ball thrown in >4 seconds) plays are removed. PFF says that these values tend to be more stable year-to-year, since they are more indicative of actual pass rushing ability.
Let’s start by examining edge rushers, where the Bears have three notable NFL veterans: returners Robert Quinn and Trevis Gipson and newly signed Al-Quadin Muhammad.
The table below shows how all three fared in a variety of pass rushing stats in 2021, as well as their rank compared to 93 NFL edge rushers with at least 200 pass rush opportunities. To give a broader frame of reference, the best, average, median, and worst values among that 93-player sample are also provided for each statistic.
Categories highlighted in green indicated the player was in the top 25% of edge rushers (top 23), while red indicates the player was in the bottom 25% (bottom 23).

Before officially demoting Teven Jenkins to the second team, Matt Eberflus and the offensive coaching staff should try him at right guard.
Jenkins’ demotion was a surprise because, if the Bears had any questions about his ability to play right tackle, why didn’t they do more to address the position in the offseason? As it stands, the team promoted fifth-round rookie Braxton Jones to left tackle and moved 2021 fifth-rounder Larry Borom to right tackle, with Jenkins taking snaps with the second team.
Eberflus has said it was always part of the team’s plan to move players around, but that excuse doesn’t make sense for a variety of reasons. For starters, the team didn’t even have Jones until the draft. If they planned on having a draft pick seriously compete for playing time, they would’ve spent an earlier pick on the position. Secondly, it isn’t as if Jenkins is in a rotation, he was firmly on the second team, with Borom switching positions to take Jenkins’ starting reps. Lastly, the idea that they’re getting a good look at offensive linemen at this point is flawed because they have yet to see the players do any blocking.
It’s hard to figure out how Jenkins could’ve lost the job or why they made the move at all, but — anyway you figure it — it doesn’t look good for Jenkins’ 2022 outlook, at least not at tackle.
There is so much we don’t know, but assuming Jenkins is physically capable of playing, the team would be wise to try him at guard instead of forcing a competition at tackle.
Again, I am pretty obviously a fan of Justin Fields. But the behavior of those defined as #BearsTwitter goes beyond fandom. They seem to have an emotional stake in his success, as if his failures on the field would have personal ramifications for them. They make bold (odd) pronouncements about him “owning” the league and winning Super Bowls. They have constant, meaningless fights with other fans. Every Bears fan wants Fields to succeed because his success means success for the franchise. But fans never behaved this way for Cade or Rex or Jay and certainly never for Mitch. What is so different about this player?
