Introducing True Sack Rate (TSR): A film project to quantify sack production
trenchwarfare.substack.com
From a team perspective, all sacks are positive for a defense, but they can mean very different things for an individual pass-rusher making the play. Depending on a variety of different factors, player evaluation based on raw sack statistics can often be misleading.
First great read, always something I wondered about, but often only here analysts differentiate sack value during draft time.
Sometimes edge-rushers play on the inside, particularly on 3rd down or long yard situations. I.e. Brandon Graham likely does it a couple times a game or 10% or more of his snaps. So does your metric include those pass rushes. And are those pass rushes part of the snaps and snap % tally. Omitting interior sacks but including the play as part of snaps/snaps % creates a variance. Tracking both would be more time consuming as you'd have to track by inside vs outside pass rush for each play vs watching just sacks. Either way it'll would skew the metric based on positional analysis so a note may be required until you start the "interior sack production analysis"
This is a great article. One thing, why use snaps/ sack and not pass rush snaps/ sack. & bigups to Jon Ledyard I fell in love with his work at Steelersdepot
A possible suggestion , when computing metrics such as most HQ sacks or snaps/HQ sacks RHQ sacks could also be added . For eg : Myles Garrett could have 1 HQ sack every 49.2 snaps and not 55.7 snaps . Similarly joey bosa's HQ sacks metrics do not look as good because 2 of his sacks go into RHQ total
What do you think about Chase Young? I'm a fan of his and the WFT, but he doesn't ever seem to get around the edge when he is 1 v 1...Do you think he will get better?
This is great. I’ve been wanting someone to make a list like this for a while. Bc watching different edge rushers, you can tell not all sacks are the same. But it’s impossible to put into words. Great analysis
Been a long-time fan of your work, Brandon. This is an exciting and much-needed improvement over current Lineman grading systems from certain platforms that shall not be named haha.
My question: will a similar metric quantifying pressures/QB hits be created as well? Or will it just eventually be implemented to the TSR?
Do you have any grading on Ngakoue? Curious as I believe most of his sacks in 2020 have been LQ.

Regardless, again, great job!

Why is a strip sack scored so low, it seems to be a greater value to the team, and very well may employ all the skill of an HQ sack?
is there a way to view the full list of sack scores? great article btw!
Are you sure your formulas are correct? It looks like it is count RHQ as 0.25 instead of 1.25

This information is amazing. I always try to look at 1 on 1 wins but who your opponent is matters. Thanks for this!
