*Attempting to Assign Defensive Value

[MSombrero]

Sorry, the formula is proprietary. With DL what I did do is attempt to adjust for run defense, for example a tackle after a 2 yard run should be worth more than a CB getting a tackle after getting burned for 30 yards. The QB pressures thought did come to mind, but I figured I weighed sacks enough for the DL. What you said I agree with, they add value that doesn't show up on the stat sheet, they help others succeed. Tough to quantify.

Thinking about it more the defensive formations GMs use could play a role in it. Defensive linemen in a 3-4 defense will definitely have less counting stats, and there's obviously only 3 of them.

No worries. How are you collecting the data for this? I've been looking at the csv files but I can't see anything which would show you how many yards are made before a tackle. Are you scraping the log file?

I'm also guessing a lack of negative statistics for defensive backs helps bump them up. We have missed tackles but I think that's more likely to effect lineman and linebackers than DB's, and we're missing things like passes allowed into their coverage.
