Same here, although I continue to think he's not being put in the best situation given the lack of playmakers.
That said, his problems all stem from slow processing speed, which was an issue in college and is a hard thing to correct as a pro. His accuracy issues result from poor mechanics which result from delayed processing - he has less time to set his base, because it takes him too long to recognize where to throw it. He's just not reading defenses well enough or quickly enough and it's troubling that it's still going on after 20 games. Should he get another 20 games? Absolutely. But as I've said, in the meantime I'd draft or sign a developmental guy, someone with lesser tools but faster processing speed (a Minshew/Kyle Allen type).
