Each side is ranked separately, so pass defense runs 1 to 32 and run defense runs 1 to 32 independently. A team can be a top pass defense and a bottom run defense at the same time.
Not built yet. This section will hold oline_proxy — pressure rate allowed, sack rate allowed, yards before contact per rush, stuff rate and a composite rank. PFF grades, FTN adjusted line yards and ESPN block win rate are all paid or have no clean feed, so this table uses the free yards-before-contact proxy defined in the instructions and is never labeled as any of those.
