Going to agree with you here. With the beating he's taken the last couple weeks, combined with his hip surgery for someone of his age (especially in NFL years), I think it is altering the trajectory of his throws, thus damaging his effectiveness. Using your examples, and what I have seen, his level of play has been down of late. It was also very high from the previous stretch of time, so having his high's and low's side by side might influence that perception even more.
But focusing on the main area of concern for any Cardinal fan, the wear and tear of this season (Hip, Concussion, General Body Injuries) is likely messing up his timing. For the hip, when you drop back, your left hip is a central balance point to deliver the ball. It is also one of the most exposed areas that is still legal to hit on a QB. If you are weary of landing on that front hip delivering the ball, it's going to sail on you big time, which has happened to him lately.
With the division won, they should consider limiting his time out there, and give the snaps to Matt Leinart and Antrel Rolle. Yes, Rolle for the sake of entertainment. And so that someone lays him out. :lollol:
