Good post Kelso. I really don't care about throwing mechanics. There are all sorts of people who succeed in their task with poor technique, be it guitar players, pitchers, or QBs.
What I care about is the result. Consistenty zipping balls on a rope that sail 10 feet over a receiver's head - despite him being wide open and square to the QB, pretty much tells me all I need to know.
I read a post yesterday in which a poster praised him for his deep ball accuracy. And yes, on balls where he throws it up and lets WRs run under it, he looked pretty good. But you'll die a quick death if your offense is incapable of consistently completing short and intermediate high-percentage passes.
I've also read that the OL is JP's biggest hurdle. I'm generally the first one to agree with that line of thinking, but I just can't buy it in this case. He's at his worst when he's in the pocket. You can literally see him bounce higher and higher as his happy feet get the better of him the more time he has. It's rather obvious to me that he's too dang squirrelly in the pocket. In fairness to him, it may be conditioning from his days in Tulane.
He seems to be his best when he's on the run on rollouts, naked bootlegs, or just when he's running for his life on a broken play. IMHO, you have to be able to throw from the pocket to be successful. The rest is a bonus. JP is unable to throw consistently accurate passes from the pocket, and he won't be a consistently good QB until/if he does.
Just my opinion...
