The Bears had the best pass defense in the NFL last season, finishing 7th in yards, 1st in yards/attempt, 1st in interceptions, and 1st in passer rating against. Now I want to look at the performance of each individual player in coverage, using stats from The Quant Edge.
Where They Lined Up
Let’s start by taking a look at where the CBs lined up. I’m only looking at the CBs here because all of the LB are listed as “LB” and all of the safeties “FS” for pretty much the whole time, thus those designations aren’t particularly helpful.
Pretty much the only point I wanted to make here is that the Bears played their CBs in specific spots, not against specific match-ups. Kyle Fuller covered the left (right side from offense’s perspective), Prince Amukamara the right, and Bryce Callahan the slot. Toliver filled in for Prince when he was out hurt (and some for Fuller late in blowouts), and McManis for Callahan.
Of course, Callahan is now gone, so it’s worth noting that 89% of Buster Skrine’s snaps came in the slot in 2018. It’s reasonable to think that will be his role in Chicago as well, but he has played outside a good bit in the past, so maybe he moves if Fuller or Amukamara get hurt and the Bears like McManis or Duke Shelley at nickelback.
It’s also fair to wonder if new defensive coordinator Chuck Pagano will ask his cornerbacks to move around a little bit more. When he was the head coach in Indianapolis in 2017, no cornerback played more than about 90% of their snaps in one spot. That’s still mostly intact, but not the 98%/99% Fuller and Amukamara had.
Now let’s look at how well each player did in coverage. The table below shows that data for every CB, S, and ILB who played a meaningful role in 2018 (OLB are excluded because they saw very few targets due to rushing the passer more than dropping into coverage. Yes, even Leonard Floyd). Positions are color coded to make tracking the table easier.
