Yeah, at times it looked like he was shot putting the ball for some reason. But talk of a shot shoulder is false, IMO. Check out this clip from the Houston game in November:
That shows that he still has the arm strength (didn't even get to set his base and the ball still went 50 yards in the air).
What was off was the rest of it....poor accuracy (I even think he was supposed to hit Byrd running inside, but Byrd adjusted), poor pocket awareness (took a lot of bone crushing hits), and poor pre-snap blitz recognition. All of that can be fixed with more reps and better weapons, IMO. Hell, Brady has been a Buc longer than Cam has been a Patriot....Brady became a Buc around March 19th last year...Cam wasn't even in Foxboro until June and got hit with COVID in week 4 on top of no real camp....
I am not saying Cam is an elite, but honestly I agree that there aren't 32 better starting QB's...and he can still run the ball...12TD's ain't nothing to sneeze at.
