And the 2nd paragraph beyond that talks about how they can't seperate WR from QB but they specifically say it's very clear in their regression analysis that both play a big part in completing a pass, but it's nearly impossible with just play by play data to mathematically decipher how much to attribute to who.
And that's exactly the flaw with individual DVOA. And I think alot of stats to an extent sort of miss alot of the contextual stuff. Like throwing a few yards short of the marker on 3rd down is probably not a great idea. However, throwing it short of the marker to a tightly covered TE with no RAC skills is alot dumber than throwing a WR screen to the edge where you have blockers to say Tyreke Hill.
And that's some of the stuff that the stats miss out on. We've gotten great at calculating stuff like seperation and expected completion percentages and all of that stuff, but the contextual stuff is still missing. But DVOA in particular really peels out any sort of teammate context. They do a solid job of providing opponent context, but teammate context is super important.
