Kenny Pickett came with obvious shortcomings, even his most ardent supports (and I feel like I've been lukewarm to warm) acknowledge that.
But for me - and, I suspect, a lot of folks - we were just never going to get a full sense of Pickett as an NFL QB with the coaching he was getting (and, likely, will continue to get through the end of this season). Instead of designing an offense that made use of his strengths and attempted to improve his weaknesses, both were simply mitigated if not ignored.
The counter, of course, is that the NFL isn't a developmental league and KP is old for a young QB so why should he require extra teaching? The fact that other teams do develop QBs, sometimes with success, makes it clear it's a thing that can be done. And in this case, it wasn't.
Let's hope that, if nothing else, changes.
