I’ve been tracking explosive plays for a few years now because they have a strong relationship to points scored. To put it simply, good offenses produce plenty of big plays. Let’s look at how Chicago did in this department in last season.

Basic Overview

The table below shows how many explosive passes, runs, and total plays the Bears produced in 2020, as well as how those results ranked compared to the rest of the NFL. Explosive passes are those that gain 20+ yards, while explosive runs gained 15+ yards. All data is from Pro Football Reference, and explosive play data is from the Game Play Finder.

A few thoughts:

• If these results look awfully familiar, it’s because they are. The Bears were the least explosive team in the NFL in 2019 with 49 explosive plays. If you want to look on the bright side, this year actually showed a slight improvement, though they were still one of the least explosive offenses in the league.
• You can view the full results here, but Chicago’s totals put them right in line with teams like the Washington Football Team, Giants, Jets, and Bengals. Yuck.
• I found last offseason that there is very little year-to-year correlation for explosive plays. Based on this, you could argue that finishing horribly in this category 2 years in a row is random bad luck, but I’m more inclined to think it’s an indictment on the personnel and/or scheme.

Explosive Players

I also want to look briefly at who produced the explosive plays. I want to caution that I’ve found there is very little year-over-year consistency in these results, so a player having an explosive or non-explosive 2020 doesn’t necessarily guarantee it will repeat in 2021.

Let’s start with a look at the quarterbacks, and I want to note that passes here include sacks for a more accurate reflection of total pass plays.

After yesterday’s piece highlighting the Bears’ need to prioritize keeping Allen Robinson around this offseason, today will build on that with a closer look at Robinson’s value to the Bears. I’ll start with examining his individual performance, and then look to the importance of that performance in context to building a roster.

High Volume

To start with, Robinson is the team’s highest volume pass weapon by a wide margin. More than 1 in 4 passes the Bears threw last year went Robinson’s way, and he finished 3rd in the NFL in targets with 151 (9.4/game). Nobody else had more than Darnell Mooney’s 98 (6.1/game). Replacing that kind of volume would be difficult.

However, you could reasonably argue that high volume is not indicative of quality. In fact, if Robinson drew a lot of targets but had limited production with them, it could be argued that distributing those targets elsewhere is a good idea. And at first glance, Robinson was not a terribly efficient target.

• Although Robinson was 3rd in the NFL in targets, he was 6th in receptions and 9th in yards, which means other players around the league out-produced him while needing less volume to do so.
• Of the 42 players who saw 100 targets in 2020, Robinson ranked 21st in both catch % and yards/target, meaning he was middle of the pack in efficiency.

It is important to remember, however, that a pass catcher is dependent on their quarterback, and Robinson was working with bad quarterbacks last year. The players who caught more passes than him were catching balls from Josh Allen, Kyler Murray, Aaron Rodgers, Derek Carr, and Patrick Mahomes. Those who finished with more yards caught passes from those QBs plus Russell Wilson, Kirk Cousins, and Matt Ryan.

High Efficiency

With that in mind, let’s compare Robinson’s efficiency to the rest of the team’s pass catchers. The table below shows the basic statistics for every player with at least 10 targets in 2020.

The 2020 season is behind us, and now it’s time to start thinking about what changes are coming in the offseason to prepare for next year. We will focus on the roster, examining the salary cap situation, looking at who’s still under contract vs. a free agent, and exploring potential options for freeing up money.

Salary Cap Situation

The 2021 salary cap is currently projected to be somewhere between $175 and $195 million. I’ll use $185 million, right in the middle of that, as our estimate for now. As you can see in the table below, the Bears are fairly tight up against the cap right now (bottom row). All numbers come from Over the Cap.

The Bears have very little cap room, and it’s worth noting this is with only 45 players under contract. The Bears will have to fill to 53 for a full roster, and the NFL minimum salary is $660k. Even if they fill out with minimum-salary players, that adds another $5.3 million, which puts them over the salary cap (or very close to it, depending on where exactly it ends up). That’s not to mention their draft picks, which will add a few million to that; the Bears pick 20th in round 1, and last years’ 20th overall pick had a $2.4M cap hit.

I’ll note these numbers are current as of about 10 PM Chicago time on Wednesday, January 13. They might have changed if the Bears sign more practice squad players to futures contracts (which basically adds in guys at that minimum $660k level).

Depth Chart

So the Bears are currently a little over the salary cap, though there are always options to free up more money (more on that later). Who do they have under contract making all that money? The table below shows the current depth chart for all 45 players currently signed for 2021 (again, might be a little out of date as the Bears sign their practice squad players in the upcoming days).

Yet again in 2020, we see that the Bears have one of the best defenses in the NF,L coupled with one of the worst offenses. This combines to give them a team that is not good enough. It’s Groundhog Day all over again, a continuation of 2018-19, all of the Lovie years, and the 1980s after Jim McMahon got hurt.

Normally I’d use the bye week to do an in-depth look at the numbers for Chicago’s offense and defense, but honestly I don’t see the point. Their defense is really good, their offense is really bad, and you don’t need advanced stats to tell you more than that. I’m sure I’ll still do some of that analysis in the offseason but for right now I want to focus on a bigger question: WHY is the defense so much better than their offense?

The answer here is really not that surprising: the Bears are investing more in the defense. The table below shows how much money they have invested in the defense compared to the offense, as measured in 3 ways:

• 2020 cap dollars. How much current money is being spent.
• Average yearly salary. This accounts for the fact that contracts don’t have even distribution of cap hits every year. For instance, Robert Quinn has an average salary of $14M per year in his contract, but only has a 2020 cap hit of $6M. This will give a better picture of true spending.
• % of salary. This looks at how much of your total spending is focused on one side of the ball, based on the average annual salary of players. It’s a good measure of how lopsided your investment is on offense vs. defense.

The table below shows the Bears’ values for offense and defense in each category, as well as the NFL average and where the Bears rank. All data is from Spotrac.

A few thoughts:

I already looked at a variety of statistics for the offense, including QB performance, run game woes, and explosive plays, and explored how Chicago has deployed their skill position players. Today I want to look at advanced defensive statistics from Pro Football Reference and think about Chicago’s playoff odds.

Missed Tackles

I highlighted missed tackles as a concern in the secondary heading into the season. As a team, the Bears are actually doing quite well with missed tackles right now; they rank 7th in the NFL with 22 through 5 weeks. The table below shows missed tackle stats (from Pro Football Reference) for all players with at least 10 tackle attempts, as well as cumulative totals for each position group.

For context, here’s how the positional averages compare to NFL peers over the last 2 years:

• The median starting NFL DB misses right around 11% of their tackles, so Chicago’s secondary is about average here so far. That’s actually pretty good for them given the tackling concerns heading into the season with Kyle Fuller, Buster Skrine, and Eddie Jackson. Fuller in particular has struggled so far this year, but everybody else has been ok.

I already looked at a variety of statistics for the offense, including QB performance, run game woes, and explosive plays. Today I want to explore how the Bears are deploying their skill position players, using lineup data from the NFL Game Statistics Information System. This tracks how many plays the Bears have played with different combination of 11 offensive players, and splits the data into runs and passes, with yards gained for each. Combing through this data can provide valuable insights into how the Bears are deploying their personnel, and what packages have been most and least effective.

Tight Ends

The Bears completely overhauled this position in the offseason, following a disastrous 2019 campaign in which no player even hit 100 receiving yards. They gave Jimmy Graham a big contract, spent their 1st pick (43rd overall) on Cole Kmet, and brought in veteran journeyman Demetrius Harris.

I want to start by looking at Cole Kmet, who has been very quiet so far as a rookie despite receiving a good bit of training camp hype. Through five games, Kmet has played 102 snaps, seen 3 pass targets, and caught 1 ball for 12 yards. This is hugely disappointing, and worrisome for his future; when I looked at rookie seasons for TEs drafted in the 2nd round this offseason, I found that tight ends who are going to be good are typically involved in the offense right away. The only tight ends drafted in the 2nd round over the last 10 years to receive fewer than 30 targets in their rookie seasons are Vance McDonald, Adam Shaheen, Gavin Escobar, Drew Sample, and Troy Niklas. Of those, only Vance McDonald has done anything in the NFL. Kmet is currently on pace for 10 targets.

It’s fair to argue a rookie should see their production increase as the season wears on, so I looked at all 19 players in that study through the first five games of their rookie season. You can see the full list here, but Kmet has the 3rd fewest targets, least amount of catches, and the least number of yards through that time period. And for all of those categories, the bottom four (not including Kmet) are from the list of five names above. It’s early, but right now Kmet most closely resembles Troy Niklas and Adam Shaheen, which is very not good.

Because I was curious about Kmet, I split out lineups involving him vs. those who don’t, and also sorted by the number of tight ends on the field. The results, as you can see below, are certainly illuminating.

We’re five weeks in to a wild season in which we’ve already seen the Bears make a quarterback change and post three comeback wins from 13 or more points down. Since they’re on a mini-bye following their Thursday night victory over Tampa Bay, now is a good time to take a step back and see what we’ve learned so far.

Obligatory warnings:

• These are still small sample sizes, especially given that each QB basically played 2.5 games. So think of any lessons learned here more as observations that are worth monitoring going forward than hard and fast conclusions.
• Statistics for Bears are updated through 5 games, but all other teams only have 4 at the time of this writing, so NFL ranks may have changed a bit by the time this is published.

I have a lot I want to get to, so let’s dive right in.

Better Lucky Than Good

The Bears may be 4-1, but I don’t think anybody would argue they have played well so far this year (including Matt Nagy). As you can see from the pie chart below, which shows the % of offensive snaps the Bears have taken in a variety of score situations, they have actually spent the majority of the season trailing.

They’ve taken 2/3 of their offensive snaps while trailing (33% by 2 or more scores) and only 19% with a lead. To somehow go from that to 4 wins in 5 games is remarkable, but it should not be expected to continue going forward. The Bears need to play better if they want to keep winning games. The good news is that they started to look better in week 5; the defense in the 2nd half looked the best it had since week 4 of the 2019 season, and the offense was something approaching competent for the last 40 or so minutes of the game.

QB Comparison

The Bears switched from Mitchell Trubisky to Nick Foles in the 2nd half of week 3, which means both QBs have actually played a similar amount of snaps so far this year (Foles is at 168, Trubisky 169). Let’s see how each performed. The table below shows stats for each passer, as well as the average for the entire NFL this year, broken up into deep and short throws (anything that travels 15+ yards in the air past the line of scrimmage is considered deep). YPA = yards per attempt.

A few thoughts:

• Keep in mind that Nick Foles has played 2 of the best defenses in the NFL the last 2 weeks, while Trubisky played all of his snaps against 3 of the worst defenses in the league. Still, it’s hard to argue Foles has been better so far, at least on a statistical basis. He needs to play better going forward.

It has been the strangest off-season in the history of the NFL. Now, the folks around here attempt to predict how the regular season will go. And there’s plenty of reason for optimism.

10-6, Playoff Berth.

This should continue to be one of the best defenses in the league, and the offense should be better than last year, but QB issues still limit their ceiling, and I’ll be surprised if the offense finishes better than around 20th in the NFL.

I’m also seriously concerned about the lack of depth at a number of key spots, including offensive line, edge rusher, inside linebacker, and cornerback.

Still, there’s enough talent on this roster that I have a hard time seeing them fall much below .500.

I’m certainly planning on enjoying this year as much as I can, because I think this is likely their best team until at least 2023.

9-7, Wild Card Loss.

This season could go very wrong or it could go very right, why not split the difference?

There is a world in which the quarterback play is just good enough. Trubisky has learned to read defenses and has made enough fundamental improvements to hit the open receivers. Or Nick Foles comes in and plays like he did for the Eagles.

They have talent around the quarterback and will unquestionably be improved at right guard and tight end. If the rest of the offensive line can play like it did in 2018 and the zone blocking scheme clicks, the running game could be explosive.

Defensively, they have arguably more talent than they did in 2018 when they were the best unit in the league. At the very least, they’ll be able to chase quarterbacks and that should lead to a ton of takeaways.

They can ride their defense to the playoffs and hope one of the quarterbacks gets hot like we have seen many times before.

I’m continuing to look at Chicago’s defense using advanced defensive statistics from Pro Football Reference (PFR). I already looked at missed tackles, and today I want to look at coverage.

Baseline Rates

There are a whole host of advanced coverage stats available, including completion percentage, yards/target, target depth, yards after catch allowed, TDs, INTs, and passer rating. In order to keep it simple, I’m going to look only at yards/target, as that is a good baseline metric for how effective teams are when targeting a player. I’m intentionally not looking at passer rating because that gets skewed by touchdowns and interceptions, which are notoriously random statistics within a small sample size like this.

I compiled all yards/target stats from the PFR database for 2018 and 2019, the only 2 years it has, and sorted them by position. In order to compare starters to starters and avoid rates skewed by backups, I assumed a base nickel package of 4 defensive linemen (DL), 2 linebackers (LB), 3 cornerbacks (CB), and 2 safeties (S). For all 32 teams over a 2 year span, this would mean 128 LB, 192 CB, and 128 S. This gave thresholds of 30 targets for LB, 40 for CB, and 20 for S.

Looking at those sample sizes, you can see the spread of missed tackle rates in the table below for each position group.

After a disappointing 8-8 season, Ryan Pace moved aggressively this off-season to revamp the Bears for 2020.

On defense, he re-signed Danny Trevathan, upgraded Leonard Floyd with Robert Quinn, signed Tashaun Gipson as a cheap replacement for HaHa Clinton-Dix, and drafted Jaylon Johnson to replace the aging Prince Amukamara.

On offense, he traded for Nick Foles to compete with upgrade Mitchell Trubisky, replaced oft-injured veterans Taylor Gabriel, Kyle Long, and Trey Burton with Ted Ginn, Germain Ifedi, and Jimmy Graham, and drafted Cole Kmet to hopefully give Chicago their first long-term solution at tight end since Greg Olsen was shipped out of town a decade ago.

That’s an impressively long list of moves for a team that entered the off-season with surprisingly low amounts of cap space and draft capital. And it has left the Bears with what appears to be a pretty solid roster, at least on paper, though it’s fair to say that questions at quarterback certainly limit the optimism.

But things start to look much more questionable when you gaze beyond 2020. You see, the only way Pace could spend money this off-season was by borrowing from the future salary cap, and he did that quite heavily. Several players have had their contracts restructured within the last year+ to clear up immediate cap space by moving money to 2021 and beyond. This totaled around $20M from a combination of Khalil Mack ($7.8M), Kyle Fuller ($4.5M), Charles Leno ($4.2M), and Cody Whitehair ($3.2M).

On top of that, most contracts Pace handed out this off-season were absurdly back loaded.

• Robert Quinn has a $6M 2020 cap hit on what is essentially a 3 year, $43M deal (a 2020 savings of over $8M from the average cap hit for the deal). The downside is he will still have total cap charges of $37M remaining in 2021 and beyond, and will likely only play in Chicago for 2021-2022. To make matters worse, those will be his age 31 and 32 seasons, when his play will likely start to slip. He’s a speed rusher that relies heavily on that one skill, so it’s possible that decline will be very pronounced.
• Danny Trevathan has a $4.2M 2020 cap hit on what is essentially a three-year, $21.7M deal. That saves about $3M in 2020 cap, but means the Bears will still have $17.5M on cap charges for his remaining 2 seasons, in which he will be 31 and 32 and likely start to see his play decline.
• Jimmy Graham has a $6M 2020 cap hit on what is essentially a one-year, $9M deal. That saves $3M in 2020, but means the Bears will have that cap hit in 2021 when he is likely not on the team (if he is on the team, he’ll have a $10M cap hit, which is not ideal for a player who will turn 35 during that season and has already started showing signs of decline).
