*Attempting to Assign Defensive Value

[Modern_Duke]

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.

I’ve long said tackles are actually a negative stat, since it means you allowed a reception. But that would really only apply to CBs playing on the outside, not so much NBs and safeties
