What Changed in the Rush Game: Volume I

| January 15th, 2020

Chicago’s rushing attack was woeful in 2019, finishing 27th in the NFL in rushing yards (91 yards/game), 29th in yards per attempt (3.7 yards/carry), and 26th in success rate on rushing attempts (44%). All three marks showed a decrease from 2018, when they were 11th (121 yards/game), 27th (4.1 yards/carry), and 10th (48%) in those three metrics.

This happened despite having fairly decent consistency in personnel. The starting offensive line was the same (when healthy), and the Bears saw only three primary rushers in both seasons. Tarik Cohen and Mitchell Trubisky were 2 of the 3, with the main rusher changing from Jordan Howard in 2018 to David Montgomery in 2019.

Today I want to look at the running game from a variety of angles to try and figure out what changed to account for the dip in production.


Player vs. Player Comparison

Let’s start out by comparing each player from season-to-season. First, I’ll look at the players who accounted for the majority of rushing attempts each year: Jordan Howard and David Montgomery. Their usage and production was remarkably similar in the two seasons, as you can see in the table below.

Similar playing time, similar carries, similar efficiency. The two were basically indistinguishable from each other, at least on the surface. That really makes you question whether it was worth getting rid of Howard and trading up for Montgomery in the 3rd round last year. At least for 2019, the answer is a resounding no.

This post is focused on rushing, but look at those bottom two rows. One of the reasons to swap Howard out for Montgomery was supposed to be that Montgomery can feature more heavily in the passing game, and thus make the offense less predictable and harder to defend. That didn’t happen in 2019. One of Chicago’s big problems in 2018 was that they were too predictable based on personnel (Tarik Cohen = pass, Jordan Howard = run, Anthony Miller = pass, etc.). In 2019, the offense ran the ball 50% of the time when Montgomery was on the field and only 24% of the time when he wasn’t. For Cohen, those numbers were 25% and 52%. That’s too big of a swing in tendencies based on personnel.

Understanding the Role of Newly-Acquired Free Agents in 2019: Offense

| March 20th, 2019

The Bears have made a number of moves in free agency, and I want to use some statistics to weigh in on their likely role on the roster / value to the team. Let’s start with a look at the offense.


Mike Davis

Davis has just 238 carries in 4 seasons so it was a little surprising to see the Bears move so quickly to sign him at the start of free agency. But a closer look reveals why they did so.

A few weeks ago I identified the typical physical profile of a running back in this offense, and Davis fits the bill, as you can see in the table below. Thresholds that he failed to hit are highlighted in red.

Davis matches the profile of backs who are usually targeted for this offense. He’s short but well built and has solid acceleration (as evidenced by the first 10 yards of the 40-yard dash) and explosion (as evidenced by the jumps). This doesn’t mean he’ll magically be a stud here after being a role player in San Francisco and Seattle, but it explains a little bit about why he was on the Bears’ radar.

Another way Davis fits is in terms of his skill set. Running backs in this offense are asked to do two things: run between the tackles and catch the ball out of the backfield. The table below shows how effective Davis was doing those compared to Jordan Howard in 2018, with both compared to Kareem Hunt as an ideal (on-field) back for this system. I highlighted cells in red when one running back stood out from the other two in a bad way, and green when one running back stood out in a good way.

A few thoughts:

  • The first thing that stands out is that Davis is better than Howard at running between the tackles, where both were asked to have a majority of their carries in 2018. This can be evidenced by his significantly higher yards/carry average between the tackles last year, when he was comparable to Kareem Hunt in that regard. It’s worth noting that this trend was only really true in 2018; Davis was generally inefficient at pretty much everything prior to that in his career, and Howard had -by far – the worst year of his career in 2018. Still, the Bears are banking on getting the 2018 form of Davis, which would be a running upgrade over 2018 Howard.
  • Sticking with running, let’s take a look at success rates in the bottom two rows. This was one area where I pointed out Howard actually did quite well, and Davis did as well (again in 2018, not so much before that). Since success rate is a measure of staying with or ahead of the chains, this indicates Davis should hopefully be able to continue Howard’s success converting in short-yardage situations.

ATM: Bears Should Target Spencer Ware

| March 5th, 2019

A 230-pound back with 4.6 speed isn’t what most fans are dreaming of this offseason. But Spencer Ware, a sixth-round pick by Seattle in 2013, could be the perfect fit for the 2019 Chicago Bears.

At this point in his career, Ware is known as a backup, but he once earned Kansas City’s starting job by rushing for 403 yards  — 5.6 per carry — and six touchdowns in 2015. He held the starting job in 2016, making 14 starts and totaling 1,368 yards from scrimmage; more than Jordan Howard has managed each of the last two years. He was poised to start for the Chiefs again in 2017 before a preseason injury knocked him out and Kareem Hunt exploded. Ware reemerged late last season, rushing for 122 yards in two starts before another injury knocked him out until the playoffs.

With Damien Williams performing well in the playoffs, Ware will likely be looking elsewhere for a chance to compete for a starting gig. Where better than Chicago? On paper, he may not seem like an upgrade over Howard, and he may not be a better overall runner, but Ware can simply do things that Howard can’t. These are the things the Bears need their running backs to be able to do.



Howard excelled early in his career at running outside zone plays, cutting up the field, against the grain. With Nagy’s inside zone scheme, the Bears are asking Howard to do the opposite, to be able to take inside runs outside and he simply hasn’t done it effectively.

Mathematical Proof the Bears Need More Explosive Plays on Offense

| March 4th, 2019

I recently ran across this Tweet from NFL Matchup on ESPN – a terrific account you should definitely follow on Twitter if you want to be a better educated football fan. It got me thinking about Chicago’s offense and explosive plays.

Seeing as I’ve already written about Mitchell Trubisky’s struggles throwing the ball deep and Jordan Howard’s lack of explosive runs, I figured the Bears probably ranked towards the low end in this area. Using Pro Football Reference’s fantastic Game Play Finder, I was able to track these stats for every team in 2018 (full data here, slight discrepancies for the 17 teams shown in Tweet above, but all were within 1 or 2 plays).

As you can see in the table below, the Bears did indeed not do very well when it came to explosive plays.

We can see here that the Bears were slightly below average in every category, meaning there is need for improvement in explosive plays across the board. I’ll also note that percentages are calculated simply: (explosive plays/total plays)100; I figured this might be a useful metric since there is a some difference in how many plays teams run, especially when you split it up into run and pass plays.

Jordan Howard’s 2018 Struggles Get “The Data Treatment”

| March 1st, 2019

It’s no secret that Jordan Howard struggled in 2018. DBB’s Andrew Dannehy detailed those struggles in a column a few weeks ago. Despite getting 250 carries – 6th most in the NFL – he didn’t reach 1,000 yards thanks to a dismal 3.7 yards/attempt, the 4th worst average of the 23 running backs who averaged at least 10 carries per game.

And lest we be tempted to blame this on Chicago’s offensive line, it’s worth pointing out that the Bears were 5th in total yards gained before contact and 9th in yards/carry before contact, per ESPN’s NFL Matchup. Tarik Cohen, who ran behind the same offensive line, averaged close to a full yard per carry more than Howard (4.5 vs. 3.7).

So I don’t think it’s fair to blame Chicago’s offensive line for Howard’s struggles. It is worth noting that Howard averaged only 1 yard before contact this year, one of the lowest marks in the league (PFF). Tarik Cohen averaged 2.3 yards before contact, one of the better marks in the NFL. So I think that stat says more about Howard (and how he was used) than the offensive line.

To figure out where it all went wrong for Howard, I took a closer look at a few different advanced metrics used for running backs. The first is success rate, which can be thought of as a measure of staying ahead of the chains. A run is successful if it:

  • picks up 40% of the yardage needed on 1st down
  • picks up 60% of the yardage needed on 2nd down
  • picks up 100% of the yardage needed on 3rd or 4th down

ATM: Out of the Hunt. So Now What?

| February 13th, 2019

The Chicago Bears won’t be signing Kareem Hunt. The great debate ended before the offseason officially began, as the former Kansas City Chiefs running back, facing disciplinary action from the league for a history of violent behavior, signed with the Browns. Time will tell if he’s worth the trouble for Cleveland, but the Bears still need to add some explosiveness to their backfield if they hope to improve their run game.

Because while Jordan Howard is a good player, the Bears simply need more. Forget for a second his sub-4.0 yards per carry number. The Bears offense just didn’t function well with him on the field.

  • According to NFGSIS, the team averaged 4.78 yards per play in the five most frequently used lineups in which Howard was used.
  • In the five most-used lineups that didn’t include Howard, they averaged 6.8 yards per play.
  • The big difference came in the passing game, where they averaged 7 yards per pass play without Howard and 4.92 with him.

Matt Nagy seems to know it too. In the playoff game he used a formation with three wide receivers, one tight end and Cohen over Howard 21 times. Their next most-used formation was used five times, that also didn’t have Howard in it. Howard played just 22 snaps — 34% of the team’s total — against the Eagles. From a football perspective, signing Hunt would’ve been the easy move, but not one the Bears could make without knowing his availability. Now, they have to figure out something else.

ATM: Signing Hunt to Bolster Rush Attack the Clearest Path to Super Bowl

| February 5th, 2019

Sometimes the best moves are the most difficult.

The biggest no-brainer of this 2019 NFL offseason is for the Bears to sign Kareem Hunt. From a strictly football standpoint, Hunt must be their top target. But, of course, it’s about more than strictly football. Those arguments were made by Jeff here and Emily here.

What we learned from the 2019 NFL playoffs is that running the ball is still really important:

  • The team that won the rushing battle went 9-2. The two exceptions of course were the Chicago Cody Parkeys losing to the Philadelphia Eagles and the Los Angeles Chargers beating the Baltimore Ravens, despite losing the rushing battle by a single yard.
  • Teams that ran for 100 yards went 8-1. The only team that lost was Houston, which gave up 200 to Indianapolis in the Wild Card round.

Television networks and league executives want the NFL to be a passing league, but it’s tried and true that running the ball is important and the Bears just weren’t good enough at it. Despite being 11th in rushing yardage, the Bears struggled to move the ball on the ground consistently throughout the year. They were 27th in yards per carry and all of their rushing totals were inflated by having a quarterback who could routinely run for 15 yards on 3rd-and-10.

Perhaps what’s most troubling about the Bears lack of run production is that, unlike 2017, opponents weren’t trying to stop the run. Jordan Howard faced a stacked box (eight or more defenders) on just 14% of his carries, according to NFL NextGen Stats. That’s the 13th-lowest mark in the league. The player who had a stacked box the least was Tarik Cohen, coming in at 5.05%, well below Wendell Smallwood’s 6.9% rate.

Bears Take Care of Business, Throttle Undermanned Bills

| November 5th, 2018

Strange game. From the moment Eddie Jackson returned a Roquan Smith-forced fumble for a touchdown with 7:07 remaining in the first half, the entire building knew the game was over. Here are six specific, in-building thoughts from Bears 41, Bills 9.


(1) That was one of the loudest stadiums I’ve ever heard to start the game. The crowd noise was absolutely deafening when the Bears had the ball for the first quarter plus. The false starts upfront were completely understandable. Offensive line miscommunication should have been expected. (I could barely hear a friend two seats away from me.) There is no chance a Soldier Field crowd, with the team at 2-6 and starting a dead weight quarterback, would be anywhere near that enthused at kickoff. Impressive showing from Bills fans, in and around the ballpark.


(2) Good to see Jordan Howard running with some anger. Again, don’t look at the overall numbers. They’re mostly meaningless in a game like this. But Matt Nagy is finally starting to understand how to use Howard, especially down in the red zone. The Andy Reid offense like to throw to score. The Bears are built to ride Howard into the end zone.


(3) Two defenders stood out to me: Roquan Smith and Eddie Jackson. Smith is going to be a star in the league for a long, long time but that is expected from a top draft pick. Jackson is an incredible player. He closes on the football as good as any Bears safety since Mike Brown. He’s the rare back end guy comfortable with the football in the air and tackling in the open field. He’s got great, natural instincts.


(4) The Bears were clearly uncomfortable with the amount of running Mitch Trubisky did against the Jets last week because there were times Sunday Trubisky had acres of space in front of him. If this WAS a coaching decision, I applaud it. Trubisky knows he can run. That’ll be there as long as his legs are. But this season has to be more about processing information, stepping into the pocket and delivering the football. And in a game like Sunday’s there’s no reason for the young quarterback to take any unnecessary punishment.

No Ugly Victories: Bears Beat Jets, Re-Take First Place in the NFC North

| October 29th, 2018

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.
