What I do realize is that every QB can make an errant throw. EJ misses them far more than most. I have seen him throw it too far, too short, ahead of the receiver, and behind the receiver, despite his limited time on the field. If he had trouble reading defenses, I would expect growth in his game, but that's not his primary issue. It's throwing accuracy. Not sure how that can be correctable.
For another example, Geno Smith has been a likewise disaster, but his issue is reading the D, which results in lots of picks. However, Geno's accuracy is much better when he is not fooled. No idea whether Geno will get better, but I can't see EJ, all of a sudden becoming an accurate thrower. Hopefully, I am wrong.
