And that's with a Swiss cheese OL, no Brandon Aiyuk, no Deebo Samuel, a banged-up Pearsall and Kittle missing five games.

My understanding is that QBR is supposed to account for that, isolating QB play from the other players.  So, if you scramble for 2 yards when the pocket collapses because an OL missed a block, that is considered a very positive play for QBR.  OTOH, if you throw a completion into a wide open receiver, but underthrew the receiver to allow the DB to recover, that is a negative for QBR.

Right, that's my understanding as well, that QBR is a more accurate QB measuring tool because of that explanation. So Brock at #2 in the NFL makes some sense over Jones, and I don't think the 49ers trade Jones, I think they keep him for the full two years of his contract, not even if the offer is a 2nd and 5th round pick, despite the fact that the 49ers desperately need DLs and LBs and a WR. And some OLs. They'll have seven selections in the first four rounds, so I don't see them trading Jones for anything other than a haul of picks.
