Data Entry: Breaking Down Trubisky’s Interceptions

| January 23rd, 2018

In his rookie season, Mitch Trubisky got to play 12 games and throw the ball 330 times. In those 330 attempts, he threw 7 interceptions, which is actually pretty good. That rate – an interception on 2.1% of his throws – was 12th best in the NFL among qualified passers, ahead of established veterans like Matt Ryan, Ben Roethlisberger, and Aaron Rodgers.

As that list above shows, there’s more to being a good quarterback than simply not throwing interceptions. But avoiding interceptions is an important part of a quarterback’s job; in no small part because they can be game-changing plays that make it a lot harder to win.

But not all interceptions are created equal. Sometimes it’s the quarterback’s fault, sometimes it’s on the wide receiver, and sometimes it’s hard to tell. In general, I think you can group them all into one of four categories:

  1. Bad decision. These are throws that should never be made because the receiver isn’t open and a defender has a good chance at an interception. Bears fans have seen plenty of these in the last 8 years from balls being chucked up into double or triple coverage.
  2. Bad throw. The target is open, but the pass is off target. The problem here comes not in the choice to throw but in the throw itself.
  3. Miscommunication. The quarterback thinks the wide receiver is running one route, the wide receiver runs another route, and the defensive back is the beneficiary.
  4. Receiver error. The receiver is open, the pass is good, but the ball bounces off of the target’s hands and gets intercepted.

The first two are both the fault of the quarterback, though in very different ways. The third one makes it pretty much impossible for us to assign fault. The last one is the fault of the target.

Data Responds: Bears at Bengals

| December 10th, 2017

Is this real life?

The Bears dominated on both sides of the ball, scored 30 points for the first time in over two years, and generally rolled over the dormant Cincinnati Bengals.

I know Cincinnati is bad and banged up, but so are the Bears, and this was a lot of fun. More importantly, this as led largely by young players for the Bears, which bodes well for the future. Let’s take a look at what happened.

Offense

  • The Bears came out and threw it on their first 2 plays! The first resulted in an awful Jordan Howard drop (drink), while the second was a beautiful play action rollout to Josh Bellamy for a 1st down. This unsurprisingly caught the Bengals’ defense off guard, and they backed off the defense into standard 7 man boxes instead of loading 8-9 up. As a result, the Bears ran it the next two plays for about 40 yards and a touchdown. That marked the first time this season that the offense scored a touchdown on their first possession of the game.
  • Before I get too down on Howard, how about giving it up for a great game from Chicago’s stud running back? He had his 12th 100 yard rushing game in 26 career starts and passed the 1,000 yard mark for the 2nd year in a row, making him the first running back in Chicago history to start his career that way. That’s pretty remarkable when you think of the great running backs who have played in Chicago.

Data Responds: Bears vs. 49ers

| December 3rd, 2017

The Bears led for almost the entire game, but pretty much everybody watching the game knew what was coming when San Francisco got the ball back down 14-12 with just over 4 minutes to go. The 49ers methodically marched down the field and longtime Chicago kicker Robbie Gould drilled his 5th field goal of the day to send Chicago to their 5th straight loss.

Offense

  • Chicago’s offense came out on the first possession and ran the ball twice in a row out of heavy sets. Anybody who’s watched Chicago this year can already guess how that ended: with Chicago in 3rd and long. That led to a sack of QB Mitchell Trubisky for a nice quick three and out.
  • Speaking of running on first down, the Bears did it 11 times in 14 chances today. Only one of those runs went for more than 3 yards; most went for 0 or 1.
  • It looks like any confidence rookie quarterback Mitchell Trubisky earned from the coaching staff completely evaporated after a bad game last week. They finally opened things up two weeks ago, and the offense shockingly had their best game of the year. Now they’ve had back to back terrible weeks after reverting to horribly predictable play calling.

Data Responds: Bears at Saints

| October 29th, 2017

The Bears played pretty evenly with the NFC South-leading New Orleans Saints on the road, but a series of missed opportunities (helped by one atrocious call by the officials) cost them the chance to enter the bye at 4-4.

Perhaps most important to Chicago going forward, the loss was a costly one for the Bears. Four starters left the game with injuries and did not return, including guard Kyle Long (hand), center Cody Whitehair (arm), cornerback Bryce Callahan (knee), and tight end Zach Miller (leg). We’ll wait to see how serious the injuries are, though I can say fairly confidently that Miller’s gruesome leg injury means his season (and likely his career) is finished.

Still, the best news to me from the game was that they kept fighting. When they went down 17-6 early in the 4th quarter, I expected them to roll over and quit, but from that point on the defense forced two turnovers, the offense scored a touchdown, and the special teams picked up a big return to keep Chicago in the game. The attitude on the team is changing, and the importance of that can’t be overstated.

Offense

  • The Bears were forced to ask for a bit more from rookie quarterback Mitchell Trubisky this week, and we saw some of both good and bad, as should be expected from a young quarterback. We saw the talent leading to some big plays, and we saw the rookie mistakes leading to missed opportunities and/or negative plays. The overall stat line (14/32, 164 yards, 0 TD, 1 INT, 46.9 rating) looks ugly, but his performance was not that bad. Notably, Trubisky threw 2 touchdowns, but one of them was taken away by a terrible officiating call and one of them was inexplicably dropped by a wide open Jordan Howard.
