He got a second opinion on the shoulder
Granted he's dealing with an injury now, it's unfortunate and is what it is, but you might frame this as a negative and I don't. He went back to the surgeon who operated on him and was advised to just rest. Also read it was always the plan when he reported shoulder soreness so was not a situation were more bad news/tests made him go see the surgeon.
When is he going to work on his passing?
He's been working with a QB coach this off-season. Josh Allen's guy. Might be why his shoulder is worn out?
And you're asking him to suddenly be better at passing against an NFL defense?
One thing I'd add on this. His mechanics do need work to clean up his passing but so does his decision making. For whatever reason(s) last year he was far more reluctant to take the shorter throws. So just something for people to keep in mind that he led the NFL in air yards per target last year, was over 12. That's a formula for any QB to hamper their completion percentage.
I know some people scoff at the notion he can be a 60% passer but he while the sample size was small his rookie year he was literally 4/10th of a completion from being just that. His air yards per attempt was about 4 yards less.
I'm not even remotely trying to say he does not have accuracy issues, just think some context for his incredible poor percentage last year is needed.
