Bears & Raiders in London Game Preview, Volume II: The Football Stuff (Mostly)

| October 4th, 2019

The George Inn. My favorite pub in London.


Why Do I Like the Chicago Bears This Week?

I always like the Chicago Bears.

And they are not losing in London, with Reverend Dave and I in the building, all hopped up on bitter ale.


Trite, Boring Thoughts on the Raiders (Stolen From Data’s Twitter)

Data had a stream of Tweets early in the week but I fear they were lost in the Monday excitement. He is one of the best follows on Bears Twitter and I recommend you give him a follow. Here are his thoughts:

  • Derek Carr has been sacked only 8x in 4 games this year. 4th fastest time to throw of any NFL QB, 4th shortest average throw. This feels like a game where the Bears need Roquan Smith, not Nick Kwiatkoski. Gonna be a lot of underneath stuff in coverage.
  • In the running game, Oakland runs inside a little more than outside, so in that regard Kwit would fit right in plugging the interior run. When they do run outside, the Raiders heavily favor the right by a 2:1 ratio.
  • 2 of Oakland’s 3 most targeted players have among the 15 shortest average target distances among all NFL WRs and TEs. Waller is 4th shortest TE at 4.9 yards/target, and Renfrow 3rd shortest WR at 6.4 yards/target. Together they account for about 45% of all Carr targets in 2019.
  • Looking now to Oakland’s defense, this is a game the Bears should find success through the air. Raiders giving up 8.1 yards/attempt (23rd), with 9 TD and only 1 INT for a passer rating of 106.8 (25th).
  • Some of that is because Mahomes lit them up, but Flacco and Cousins both posted a passer rating >100 against them, and Brissett threw for 3 TDs. Their pass D is bad, in no small part because they can’t rush the passer (only 5 sacks through 4 games).
  • Oakland’s run D is actually pretty solid, coming in at 16th in rush yards/game and 11th in yards/carry.
    • Editor’s Note: Dalvin Cook rushed for 110 on only 16 carries against them.

Tweet of the Week (kinda)

I found this story incredibly moving.

Recapping the 2019 Offseason

| August 19th, 2019

It’s been a long offseason, and I’ve covered a lot of ground with a variety of articles. Now that the 2019 season is fast approaching, I’m pretty much finished writing new content, but since I have a hard time remembering everything I’ve researched and shared on here, I thought it might be helpful to re-visit what we learned and see how it relates to the Bears in 2019.

I’m going to try and highlight the most relevant stuff in 1 sentence per article, grouped together by topic. Think of it like a TL;DR for the offseason.

Picking the 2010s all decade team

| August 3rd, 2019

Hall of Fame weekend has me thinking about the big picture of the NFL over time, which makes me think about decades. Every 10 years the NFL puts out an all decade team, so we’re about one year removed from seeing what that looks like for 2010-19.

Since we’re still a little ways from Chicago’s 1st preseason game on Thursday, I thought it would be fun to pick out who I think should be on the all decade team, though there are a few spots where 2019 could end up changing the pick.

I’m going to go with the most commonly used NFL personnel groupings, which on offense is 11 (1 QB, 1 RB, 1 TE, 3 WR, 5 OL) and on defense is nickel (2 DL, 2 edge rushers, 2 off-ball LBs, 3 CBs, 2 S). To keep it simple, I’m not going to worry about SS/FS, slot/outside WR, or nickel/outside CB designations.

Let’s get down to business.

QB: Tom Brady

Before even doing any research, I knew this was going to come down to Tom Brady, Aaron Rodgers, and Drew Brees. All have been really good QBs for the entire decade. Brees leads in passing yards and touchdowns, but hasn’t been 1st team all pro or won MVP in this decade. Rodgers and Brady both have 2 MVPs, 2 1st team all pros, and 1 2nd team all pro since 2010. Rodgers has slightly better individual stats, but Brady has played in 5 of the last 9 Super Bowls, winning 3 of them, while Rodgers has only played in 1. That nudges things in Brady’s direction in my book.

RB: Adrian Peterson

I went into this expecting to pick Adrian Peterson, but was surprised how difficult LeSean McCoy made this decision. Both players were 1st team all pros 2x since 2010, though Peterson has an edge in also being a 2nd teamer twice and winning an MVP. McCoy has an edge in volume statistics, however; he has about 1200 more rushing yards than Peterson, an extra 2000 receiving yards, and about 10 more total TDs. McCoy has been really good for longer, but Peterson’s peak was better, and I’ll lean in that direction. Todd Gurley is the only other RB with multiple 1st team all pro berths, but he only played in 4 of the 9 seasons and thus lags well behind the other two in volume numbers. Still, another 1st team all pro season in 2019 could put him in the discussion.

Who Benefits From an Improved Trubisky Deep Ball?

| July 24th, 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.

Bears at the Bye: Looking at the Defense Position-By-Position

| October 10th, 2018

Secondary

I’m not going to look at safeties much because there hasn’t really been any rotation there and there aren’t many stats to quantify safety play (though I will say I feel good about my preseason pick of Eddie Jackson as the defense’s breakout star). Let’s jump right to the CBs then and take a detailed look at their performance using stats from The Quant Edge.

The first thing I want to note is that Chicago’s corners don’t move. Kyle Fuller has played exclusively on the right side (from the offense’s perspective) and Prince Amukamara has been exclusively on the left. Kevin Toliver II basically took Prince’s spot on the left post-injury, though he did play a few snaps in the slot. Nickel CB Bryce Callahan, meanwhile, played a few snaps outside after Prince got hurt but otherwise has been exclusively in the slot.

Next I want to look at how effective each CB has been in coverage, as well as how much man, zone, and press coverage they’ve played.

A few thoughts:

  • At first glance it might seem like Kyle Fuller has been the worst CB on the roster, but look beyond the passer rating. That takes a big hit because he’s given up 2 passing TDs and none of the throws targeted at him have resulted in interceptions yet. He’s been very good at keeping the completion percentage down, and the yards per target on throws aimed at him are much lower than anybody else. Make no mistake: he is the best CB on Chicago’s roster, and he is very good.
  • Fuller is actually the only CB credited with giving up a TD so far this year. He gave up two, which means the other 5 passing TDs the Bears have allowed are blamed on non-CBs. Meanwhile, five passes targeted at CBs have ended up intercepted. That’s a great ratio.
  • I find the press splits interesting. Toliver has never played press, and Fuller only does it about half as much as Prince and Callahan. That’s perfectly fine; each player has their own style that is obviously working well for them so far.

Bears at the Bye: The Best Defense in Football? Sure Seems That Way…

| October 10th, 2018

Chicago’s defense has been awesome in the first month of the season. They’re among the best in the league in nearly every category that matters, and are ranked first overall in DVOA. Now I want to look a little more closely at how well they’re performing against both the run and pass in different areas of the field.


Defending The Run

Chicago’s run defense was solid in 2017, but it has been fantastic so far in 2018. They have shut opposing run games down, and they’ve done it pretty much across the board, as we can see below.

Here’s the data for Chicago’s rushing defense by zone, courtesy of the NFL Game Statistics and Information System. The line at the bottom is the line of scrimmage, runs are split into 7 zones, and attempts and yards per carry are listed for each zone, with ranks relative to the rest of the NFL in parentheses. The height of the bar is proportional to yards per carry, and bars are colored green for top 10, red for bottom 10, and yellow for middle 12. Note expected yards per carry varies by region, so the colors are relative to their peers in that region.

A few thoughts:

  • That’s a whole lot of green. Awesome. Last year’s version featured a lot more yellow and red. This is a good time to remind you that Khalil Mack is an elite run defender in addition to being one of the best pass rushers in the league.
  • Speaking of Khalil Mack, he and Akiem Hicks usually line up opposite the RG and RT. Notice where defenses are running towards? There are 38 runs to the left side – away from Mack and Hicks -compared to 21 towards them on the right.

Bears at the Bye: Pass Catchers! Everywhere! Pass Catchers!

| October 9th, 2018

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.

Bears at the Bye: What To Make of the Running Back Position

| October 9th, 2018

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.

Today we’re going to focus on running backs Jordan Howard and Tarik Cohen, examining how much they’re playing, how effective they’ve been, and how they’re being utilized.


Snap Counts and Efficiency

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

(Note: 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.)

A few thoughts:

  • Howard is actually playing typical lead RB snaps for an Andy Reid offense. As I noted this offseason, Kareem Hunt played 65% of the snaps in Kansas City last year. This is in stark contrast to the Philadelphia Eagles style-rotation I thought would make more sense. It’s worth noting the 2 split snaps almost exactly 50/50 in the Tampa Bay game. I wonder if that’s more what we’ll see going forward.
  • The run/pass splits for when both of these players are in vs. out of the game are too lopsided. A 30% swing when Howard exits the game and 20% swing when Cohen enters the game should not be the case. This is too predictable and makes it too easy on the defense.
  • Some of these numbers are related, since Howard and Cohen basically swap being on the field. They’ve only shared the field on 23 snaps so far this year, so the run game being more effective with Howard off the field is the same as saying the run game gets more effective when Cohen is on the field. Again, I think this might have more to do with defenses gearing up to stop the run when Howard is in the game and not expecting it when Cohen is in.

Bears at the Bye: The Guy Playing Quarterback

| October 8th, 2018

Now that we’ve seen Mitchell Trubisky play four games under Matt Nagy’s tutelage, it’s time to examine how he’s doing. We’ve seen him play 269 snaps and throw 130 passes, and while that’s still a fairly small sample size, it’s big enough that we can begin to analyze how he’s performing in a variety of situations.


Growth Through Each “Quarter”

Last offseason I looked at Trubisky’s performance in 4-game snapshots, borrowing the idea of breaking an NFL season down into quarters from Lovie Smith. There I found that Trubisky got progressively better in every “quarter.” Since Trubisky has played 4 games this year, he now has 16 in his career, giving him a full 4 “quarters” that we can track. Let’s take a look.

Well that looks pretty good. I said last offseason that, statistically speaking, Trubisky needed to throw more TDs while keeping everything else the same. Here we see that he has managed to throw more TDs, and everything else has stayed the same or improved. That’s good growth to see from a 2nd year QB.

Of course, four games is a small sample size, and this doesn’t look quite as rosy if we remove the Tampa game from the equation. Then his yards per attempt drops to 5.7, TD percentage to 1.9%, and his INT % (2.9%) and sack % (8.0%) both rise a bit higher than they were late in his rookie year.

Through three weeks, the stats suggested Trubisky was actually playing worse than late in his rookie year. That’s not entirely surprising given that learning a new offense often results in a step back at first.

Adding the TB game in there makes this look good, but now the question is whether the TB game was an aberration or a sign of things to come.

Bears at the Bye: Examining the Trends of Matt Nagy’s Offense

| October 8th, 2018

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.


Down & Distance

Let’s start by looking at what they’re doing in different down and distance situations. All statistics come from the NFL Game Statistics and Information System unless otherwise noted.

First Down

The offense has been extremely balanced on 1st down so far, with exactly 58 runs and 58 passing plays (passes, sacks, or scrambles).

The passing game has thrived with an average of 7.8 yards per play. According to Pro Football Reference’s Game Play Finder, Mitchell Trubisky is completing 69% of his passes on 1st down, with 6 TD, 2 INT, and a 115.9 passer rating.

The running game, on the other hand, has been extremely ineffective, averaging only 3.0 yards per carry. Most of the running attempts (34) have come from Jordan Howard, who is averaging 3.2 yards per carry, but Tarik Cohen also has 17 carries at only 2.9 yards per clip. It would appear the Bears are either making it obvious when they’re going to run or defenses are worrying about stopping the run first to make Trubisky beat them.

Second Down

When it comes to 2nd down, context is needed. A 3 yard gain is great on 2nd and 2, pretty good on 2nd and 5, and awful on 2nd and 10. With that in mind, I split the data into 4 groups based on the distance required to get a 1st down. The table below shows the results.
