What do the advanced stats say about the Chicago Bears new addition Robert Quinn?
The Chicago Bears continued their free agency moves with the addition of Robert Quinn. By adding Jimmy Graham, and Quinn, the Bears added two players who will be 30 years or older by the start of the new NFL season. This speaks to the all-in nature that they have with this roster.
The team moved on from Leonard Floyd, hoping to upgrade with Robert Quinn. Do the advanced stats say that they got a better player?
Pass Rush Win Rate
Looking at pass rush win rate, we can see why the Chicago Bears did not hesitate to add Robert Quinn. Take a look at the chart below. The chart compares the percentage of times a defender beat his man within 2.5 seconds one axis with the percent of times he faced a double team.
Robert Quinn is in the high right corner because he faced a lot of double teams but still won. Leonard Floyd is in the low left because he does not face double teams but still does not win. It could be almost that simple.
Pass Rush Productivity
Pass rush productivity is a PFF stat that looks into the number of sacks, hits, and hurries over the number of pass-rush snaps. Looking over the past three seasons, Quinn is once again superior.

In 2017, Floyd had an 8.2 rating and Quinn had a 6.3. That is the year Quinn was cut by the Rams. In 2018, Floyd struggled with his broken hand and a 4.8 pass rush rate. Quinn bounced back slightly in Miami with a 6.8 rate.
However, once again, Quinn found his legs in 2019. He had a 9.2 pass rush win rate last year while Floyd had a 5.2. Over three years, Quinn has a 7.4 productivity rate, while Floyd had a 6.1 rate. Quinn has been more consistent and had higher peaks.
Pressures
Looking at the raw totals, Robert Quinn posted 133 total pressures over the past three seasons. Floyd had 111 in that span.
Stops
Stops include running and passing plays that did not go for a successful play. Floyd had 73 over the past three seasons. Quinn had just 60. This is where we start to see a bit of the difference as Floyd was used more in space and on the edge to defend the run.
Missed tackle rate
However, Quinn still is a more sure tackler. In 2018 and 2019 Floyd had 13% and 14.9% missed tackle rates. Quinn had 10.5% and 11.1% rates in those areas respectively.
Run Stop Rate
Lastly, Floyd was a better run defender, but not by a lot. He had a 5% run stop rate. Quinn had a 2.6% run stop rate, one of the worst in the NFL.
It is clear that the big difference between Quinn and Floyd is that Quinn will not play the run or play in space nearly as well. The trade-off is that Quinn is clearly a better pass rusher. Quinn blew up in 2019, but was just good in 2018 and had his worst year in 2017. Tracking his age and productivity with a secured contract will be worth watching, but overall it is a good move.
