Today we’ll switch to look at how linebackers and safeties have fared in coverage.
Like I did with cornerbacks, I’m using data from Pro Football Focus (PFF) that looks at how frequently and effectively individual players are targeted in coverage. I chose to set a threshold of 250 coverage snaps because it both gives a decent enough sample size to judge an individual player and gives a big enough grouping of players at each position to evaluate how somebody performed relative to their peers. This threshold gave a sample size of 68 linebackers (2.1/team) and 82 safeties (2.6/team).
Linebackers
Let’s start with a look at linebackers, where the Bears return Roquan Smith and bring in Nicholas Morrow. The table below shows how they fared in a variety of coverage metrics last year, as well as their rank compared to 68 linebackers who had at least 250 coverage snaps. To give a broader frame of reference, the best, average, median, and worst values among that 68-player sample are also provided for each statistic. Categories highlighted in green indicated the player was in the top 25% relative to their peers, while red indicates the player was in the bottom 25%.
Note: Since Morrow missed the 2021 season with an injury, his data is from 2020, but he is still ranked against his peers in 2021. I know this is not perfect, but these values shouldn’t change that much league-wide year over year, and it saved me a ton of work.
A few thoughts:
- Overall, both Roquan and Morrow appear to be very good in coverage. This should be a real strength of Chicago’s defense.
- The two main stats I would use to evaluate effectiveness are yards/target and yards/coverage snap. These encapsulate a bunch of the other metrics to show how many yards the defender gave up overall.
- In those areas, Roquan is solidly above average, but not great, which honestly surprised me.
- Morrow, on the other hand, ranks near the top in both. The Bears haven’t had a good coverage linebacker to put next to Roquan since he was a rookie in 2018, so the thought of pairing him with somebody who excels in coverage is enticing.
- Some of the other stats can give us a glimpse into playing style. For instance, Roquan gives up plenty of catches (high catch %), but they are mostly very short (low target depth and air yards/catch). This is a common trade off in coverage, since shorter passes are easier to complete. Unfortunately, Roquan struggles a bit with giving up yards after the catch – though it’s not due to missed tackles – which is what brings him down overall. In general, Roquan is good at limiting the yards/catch allowed, but the high catch rate brings his yards/target and yards/snap ranks down a bit.
- Morrow, on the other hand, keeps the catch rate low despite giving up short passes, which gives him stellar coverage marks pretty much across the board.
