The (perhaps encouraging) thing is, we’ve seen JA17 take the short stuff and pick apart defenses before, so (it may be a comfort to see that) he has done it before and with regularity.
For example, last year’s opener, the first game of JA17’s with OC Ken Dorsey:

It’s just such a head scratcher why he last year was and still is now is failing to see wide open guys in the middle of the field also with regularity. I know concussion(s) is/are speculated. Perhaps he got used to the UCL injury play style. Personal life issues. DCs baiting him into misreading protection and coverage. Some combination of those. Not going to pretend like I know.
But I imagine he is very frustrated right now and hope he can channel that into picking apart the Raiders. If by 4-5 yards at a time, then so be it.
