With five games under the belt, the Bears are roughly 1/3 of the way through the season. Let’s check in on how they’re doing, starting with the offense.

Explosive Plays

I wrote this offseason about the importance of explosive plays (passes of 20+ yards or runs of 15+ yards) to an offense’s overall success, finding there is a very strong correlation between explosive plays and points scored. Chicago’s offense produced explosive plays at a slightly below-average rate in 2018, and I believed they were poised to improve dramatically in that category this year, and thus improve overall as an offense.

So far, the exact opposite has happened, as you can see in the table below.

The Bears have turned into one of the least explosive offenses in the NFL. They currently have 11 explosive passes and 2 explosive runs, and their current explosive rates would have ranked 31st and 32nd of 32 NFL teams in 2018 (I didn’t have time to compile the numbers for everybody in 2019 so far).

The run game is particularly egregious, as the lowest mark in the NFL last year was 3.1%. 1.7% is not even in the same ballpark. The Bears are 20th in average yards per carry before contact and 29th in yards/carry after contact, but I’m inclined to blame the offensive line more than the runners. Most of the time first contact seems to come not from one player in space, which might give the runner a chance to break a tackle and keep going, but with multiple front 7 players hitting the RB at the same time. It’s worth noting that the Bears’ running backs haven’t been great either though; Player Profiler ranks David Montgomery 36th among running backs in juke rate (evaded/broken tackles per carry), while Tarik Cohen is 55th. In Montgomery’s defense, he is 9th in the NFL in broken tackles per carry, according to Pro Football Reference.

I wrote this offseason that getting rid of Jordan Howard would help Chicago’s run game be more explosive, but so far they’re producing explosive plays on the ground at less than half the rate they did last year. Part of the problem is that Tarik Cohen and Mitchell Trubisky – who combined for 14 explosive runs on 167 carries last year, have no explosive runs so far this year, but David Montgomery only has 1 in his 69 attempts, and that’s far worse than Howard’s rate of 1 every 25 carries last year (which was already one of the worst marks in the NFL).

Even after Taylor Gabriel exits concussion protocol and returns to the starting lineup, Matt Nagy must find a way to keep Javon Wims on the field. The second-year WR did not dominate on Sunday. Far from it. And he certainly isn’t getting confused for Randy Moss anytime soon. But his performance against the Vikings stood out enough for him to be given a chance to help this offense escape their current rut.

His presence gives the team another big target, which could be help a quarterback who struggles keeping the ball down. Chase Daniel used Wims’ size multiple times in the game, most notably on a 37-yard lob that helped the Bears get out of the shadow of their own end zone. The pass ended up being under thrown, but Wims made a nice adjustment in the air to make it look like a back-shoulder throw. Daniel probably wouldn’t have thrown the pass if he didn’t think the receiver could win a jump ball.

Wims can adjust in the air. That we knew. But that played showed he can also get deep. He roasted Trae Waynes and it would’ve been a much bigger gain had the throw been on-target. That speed is new to Wims and something Prince Amukamara noted in the off-season:

Now we return to the list of reasons the Bears might struggle to repeat 2018’s success.

IV. Cornerback Penalties

New nickelback Buster Skrine was flagged 7 times for 107 yards in 2018. Those numbers were 14th and 7th highest, respectively, among all defensive backs.

Prince Amukamara also has a knack for drawing flags; he drew 8 for 90 yards (8th and 13th among DBs) in 2018, and had 2 more get declined.

And 2018 wasn’t an outlier for either player. Skrine had 11 flags for 105 yards in 2017, while Amukamara had 7 for 99.

You can live with having one penalty-prone player in your secondary, but two is a bit more of a concern. All it takes is one big penalty in a key moment to swing a close game.

V. David Montgomery and/or Anthony Miller

I’m grouping these two together as relatively unproven young players who will be counted on for big roles in 2019. For Chicago’s offense to take the step forward that is needed to win a Super Bowl, Miller needs to supplant Taylor Gabriel as the WR2 and Montgomery needs to beat out Mike Davis as the starting RB. I think there are excellent reasons to be high on both Montgomery and Miller, but what happens if one or both of them aren’t ready?

Davis and Gabriel are both solid veterans who are capable role players, but neither is a guy who should be a main cog in a top-level offense. Miller and Montgomery are capable of doing just that, but they could hold the offense back if they fail to prove it in 2019.

This is part of a series of collaborations between film guru Robert Schmitz of Windy City Gridiron and stats guy Johnathan Wood of Da Bears Blog. We’re excited to be working together to bring fans of both sites great content by combining our approaches.

Previously, we’ve identified the deep passing game as one area where Mitchell Trubisky struggled in 2018. He missed a lot of throws to open targets, which resulted both in a low completion percentage and too many interceptions.

However, we also showed that deep passing performance is highly variable, and thus Trubisky is likely to improve there in 2019, especially with some tweaks in his throwing mechanics that can be made to help his accuracy.

Today we want to look at what targets would benefit most from that expected deep ball improvement, should it happen. In order to do that, I used Pro Football Reference’s Game Play Finder to look at what players Trubisky targeted deep most frequently in 2018. That information is shown in the table below for all five players who were primary weapons for the Bears in 2018.

Allen Robinson was Trubisky’s most frequently targeted deep threat, but Anthony Miller got – by far – the highest portion of his total targets and yards from Trubisky on deep plays. Despite finishing 5th on the team in targets and yards, both by a healthy margin, he was 3rd in deep targets and 2nd in deep yards.

The offseason is the perfect time to do a deep dive into what exactly we saw on the field last year, so today I want to look more closely at how Chicago’s QBs performed in 2018. To do so, I’m going to compile all of the information about individual targets from The Quant Edge and use it to see what we can learn about QB play as a whole.

Before we begin, I want to note two limitations.

• This doesn’t split data into individual QBs, so unfortunately I can’t separate out the games Trubisky played and use only those. Still, Trubisky accounted for 85% of Chicago’s pass attempts in 2018, so this should still be useful to help us generally learn more about him.
• This data only includes WRs and TEs, so I will not be able to incorporate any information about the 132 pass attempts that went to RBs (and Bradley Sowell). I really wish they included Tarik Cohen in particular, considering he finished 3rd on the Bears in targets, but no such luck.

With that said, let’s get started.

Route Efficiency

How effective were Chicago’s QBs targeting various routes?

That data can be seen in the table below, sorted from most to least targeted. I also highlighted routes that were particularly efficient in green, and routes that were particularly inefficient in red.

A few thoughts:

• The Bears loved their go routes, but they sure didn’t work well in 2018. As previously noted, Trubisky had issues with deep accuracy, and maybe that was part of the problem. And you can argue there is value in go routes to back the defense off. But still, 26% completion rate is not acceptable for a route they utilize that frequently, and there were 5 interceptions thrown on go routes as well. If you’re looking for one bright spot on go routes, Allen Robinson caught 40% of his targets for over 16 yards/target.

On the surface, Anthony Miller had a quiet rookie season. He had 54 passes come his way, catching 33 for 423 and 7 touchdowns. This tied him for 127th in the NFL in catches, 111th in yards, and 16th in receiving touchdowns. On the Bears, he was 5th in catches and yards, but led the team in receiving touchdowns.

This is entirely unsurprising given that rookie wide receivers rarely have huge seasons. Last offseason I looked at all 2nd-round wide receivers drafted between 2008 and 2017 and found that the average player compiled 60 targets, 34 catches, 433 yards, and 2.6 touchdowns. Miller ended up right around those averages for everything but touchdowns, which is perfectly fine.

Now I want to look a bit more closely at that sample to see what we can learn about Miller from his rookie season, and how that might project going forward.

Thresholds Hit

In that study, I found that rookies who saw at least 40 targets and caught at least half of them tended to turn out as at least solid receivers in the NFL. Good news on that front: Miller exceeded both thresholds.

And now for an obligatory reminder from that article:

It’s important to note that hitting these thresholds doesn’t magically guarantee success, and failing to hit them doesn’t guarantee failure. It’s more that most of the players who have hit those thresholds have gone on to have success, while most of the players who didn’t hit them didn’t have success.

You can look back to see the full list of players who did and did not meet the criteria. (I’m not going to re-post it here because it’s too big.) Suffice it to say Miller finds himself on a substantially better list than if he did not meet those two thresholds, giving us reasons to be optimistic he will at least be a competent WR2 or WR3 going forward.

Thoughts Before the Press Conference

• Nobody should expect to hear Pace or Nagy address Cody Parkey’s future or the Today Show appearance. But both questions must be asked. What absolutely cannot be said today is “Parkey is our kicker next season.” This organization can no longer show blind, ignorant loyalty to an inadequate player.
• It’ll be interesting to hear how each man discusses Chuck Pagano’s addition. I suspect neither was thrilled with the game Vic Fangio called against the Eagles so it won’t be surprising for them to signal what Pagano will change on that side of the ball.
• The Kareem Hunt conversation is going to get started soon enough. Wonder if it is today. Reclamation projects are very possible in this league (See: Hill, Tyreek) and it is unlikely Hunt won’t be in the NFL next season. Unlike Ray Rice – whose career was already essentially over at the time of his incident – Hunt will only be 25 years old when the 2019 season kicks off.

Thoughts During & After

• The tone was established with Pace’s opening remarks. “Proud of what we accomplished but not satisfied” and “stay on the right track” were clearly what the GM wanted to communicate.
• Pagano. Pace made it clear the hiring was made by Nagy, not him. Nagy used the two words I expected to here: attacking and aggressive.
• Parkey was brought up almost immediately. Two things: (1) Pace sounded like Parkey was going somewhere else. (2) Nagy said Parkey didn’t mention Today Show appearance in their exit interview, and seemed displeased with the whole ordeal. He made it clear it was a “me” gesture not a “we” one. Parkey is gone.

Very strange game. The Jets didn’t have anywhere near the weapons to move the ball consistently. The Bears were just error-prone enough to keep the game competitive for three quarters. But it’s a win they absolutely needed. And unlike many recent vintages of the Chicago Bears, they got it. Rapid fire…

• Conditions were brutal for the passing game. But the Bears made the plays they needed to make. The Cohen screen set the tone for the entire afternoon but Trubisky’s brilliant throw and Miller’s brilliant catch put this game away. It was so good, I’m going to show it to you again.

• In conditions like this, Matt Nagy has to rely upon his ground attack and he seemed to figure that out as the game went on. But Trubisky also has to learn that the deep shots aren’t worth it when the wind is howling north of 25 MPH. When the first down is there, just get it, whether that means him tucking-and-running or accepting the check down option. That’ll come with experience.
• Folks can complain about Trubisky all they want, but through seven games Mitch is completing 64.6% of his passes for 1,814 yards, 15 touchdowns, 6 interceptions and a rating of 97.8. He’s also got nearly 300 yards rushing. This kind of production, and this position, simply doesn’t happen in this town. And it’s about time fans start appreciating it.
• Great, great job by the fans at Soldier Field. All of those pre-snap penalties go into the fan column.
• Jordan Howard is not complicated. You give him 20+ carries, you get big time production. No, they numbers weren’t gaudy but he single-handedly put this game on ice in the fourth quarter. He’s not been a focal point of this offense so far. He should be.
• Khalil Mack was the most dominant defender in football through four games. And now we’re seeing what this defense would have looked like if Ryan Pace didn’t make the franchise-altering trade on September 1st. They’re a toothless pass rush. Leonard Floyd is invisible. Opponents can double Hicks inside. Without Mack, this secondary is going to be under a lot of pressure when instead of Sam Darnold it’s Aaron Rodgers or Kirk Cousins or Matt Stafford taking the snaps for the other side.

Now that we’ve seen Chicago’s new offense play four games, it’s time to examine what exactly it looks like. We’ve seen them run 271 plays, and while that’s still a fairly small sample size, it’s big enough that we can begin to pick up trends, search for predictable patterns that opposing defenses might begin to pick up on, and see if there are any situations their current approach could be improved.

Now we focus on the wide receivers and tight ends, examining how much they’re playing, how effective they’ve been, and how they’re being utilized.

Snap Counts and Predictabilities

First I want to look at how frequently each target is playing, and how their presence on the field impacts the offense’s performance. Data is from The Quant Edge.

A couple things to note about the table below:

• I’m using success rate here instead of yards per play. That is to account for down and distance context. A two-yard play on 1st and 10 is bad, while a two-yard play on 3rd and 1 is good. The general idea is that a successful play keeps you ahead of the chains, but an exact definition is available here if you’re curious.
• I didn’t include Allen Robinson, Taylor Gabriel, or Trey Burton here because they’re almost always on the field; they’re all playing least 83% of the offensive snaps so far. This is more to look at the players who are situational and how they’re impacting the offense.
• Anthony Miller’s data only includes the 3 games for which he was active.

A few thoughts:

• On the surface, it looks like Anthony Miller has hurt the offense. Maybe he has. But he basically only plays in 11 personnel groupings, where there are 1 RB, 1 TE, and 3 WRs on the field, and in general that grouping has been the least efficient passing formation in the NFL. In terms of the run game, I don’t actually know much about Miller as a blocker. It’s possible that he’s not blocking well and that’s hurting the run game, but it’s also possible something else is causing the difference.

• This entire game comes down to the medical status of Adam Shaheen (pictured above) and Leonard Floyd. If Shaheen is significantly hurt, the Bears will be devastated. For weeks I’ve been writing and Tweeting about the big tight end because I’ve been told no player has more excited the coaching staff with his potential. If Floyd is significantly hurt, well, that Kahlil Mack stuff is about to get serious because the Bears are lightest on the edge.
• Back when I used to play fantasy football (my running backs were Marshall Faulk and Shaun Alexander) a game like this would have changed my entire draft approach. Why? Because it’s clear Mitch Trubisky and Trey Burton have a thing going and last night’s practice game was an opportunity for them to play pitch-and-catch against an actual opponent.
• Why give Jordan Howard nine carries in a practice game? The numbers are definitive. These star running backs have a limited number of carries/years in their bodies. They hit a career wall at thirty years old. I’d put Howard in an ice bath until after Labor Day.
• The interior of the Bears offensive line got pushed around a bit. But these guys are impossible to evaluate without scheme being involved. (And I don’t think this is their best five but that’s another issue entirely.)
• Both Isaac Yiadom & Kyle Fuller were called for the “lowering the head” penalty. In neither case was the call accurate. It was obvious during the Hall of Fame Game and it’s becoming more obvious as days go by. If the NFL doesn’t suspend this rule before the season opens and revisit it, they’re making a terrible mistake. The product has suffered terribly over the last few seasons because of decisions by the front office. This will continue that trend.
