Here's the snap reel of VJ's blocking vs the Falcons...
That said, BB's point that something is making them look at VJ over Pickens is correct.
But. That might be trying to make VJ work. That might also be an attempt to keep Pickens fresh, or even a minor disciplinary thing to encourage him to get on top of his details on blocking and route running. I don't know it's that they think VJ is an amazing blocker. But. Maybe they do think he's their best. Which is shambolic but there we go.
I would add that Smith has only ever put his WR1 out there for 80% of the snaps by and large, so Pickens isn't far below the Smith standard at 72%... but it's notably enough that some of this is probably them not being happy about some stuff from Pickens.
Which, given where the offence is right now, maybe seems a little stupid. Still, if this encourages Pickens to get more things right and pays off long term...
