Peshek: DT Metrics 1.0 (http://www.rotoworld.com/articles/cfb/46653/349/peshek-dt-metrics-10)
Thereís always a bit of uncertainty when looking at metrics with interior line players, whether thatís on offense or defense. Thereís so much going on in the trenches that it can be hard to assign blame or credit for specific plays. However, we can isolate different aspects of their game play which will allow a better look at what they each did specifically.

Compared to past pieces, this may seem light on huge charts and elaborate metrics. However, it may contain some of the most accurate metrics because it required me to go through and chart every snap of run and pass plays. That way, we can get an accurate picture of how efficient they were on a per snap basis, rather than just using totals. Remember things like pressures can be slightly subjective, so numbers may not match up to data from other services.

How well did they rush the passer?

Where did they line up?

The image below represents each playerís alignment on both pass and run snaps. The larger the circle, the more often they frequented that position in their pre-snap alignment. This should give you a feel for what type of experience they have and where their production was gained.

So Clowney was double teamed on 9% of his rushes and chipped on 16% for a total of 25% facing an extra blocker.

Listening to some on this board, I would expect those numbers to much higher. I expected closer to 100% actually. It doesn't mention triple teams though so that must be where the disparity comes in.

I asked Greg why he didn't parse plays like Stephen White did in his piece, removing screens and most quick dropbacks. He said it would be 1)too much work and 2)outside of his expertise to gauge "legitimate pass rush opportunities". I think Lawrence's numbers would be improved.

Then why even do this? If you're going to leave out important variables it's a waste of time.

You can "if" yourself to death with metrics parameters, ending up paralyzed and unproductive. Greg chooses what he sees as the more objective path to produce informative metrics, and he does a good job. An NFL position coach's metrics would look vastly different, as would an under-informed part time football fan's. You gotta draw the line somewhere.

What you do get is comparative feel, although the numbers might not be absolute, and some more unique statistics.

I've heard this more often from Clowney detractors than supporters, ironically. :P It also only accounts for pass-rushing downs, so it leaves out running downs.
