You make a lot of good points, Ramius, but I have to say that your conclusion does not add up for me. I wanted to believe that JP could be good as well, but frankly his last two performances have overdrawn the sympathy bank. At the most basic level of field awareness and good sense, he simply does not have it. We can talk all day about whether he would have had it if he had started consistently since 2005, but that is beyond moot. It is, after all, not unimportant to remember that part of the reason why he has not started consistently since 2005 is that, for one reason or another, he was unable to gain and hold the confidence of two head coaches, three offensive coordinators, and a few QB coaches. One could argue about the relative abilities of those coaches as well, but even then, the fact remains he was unable to gain and keep the confidence of people who saw him in practice, who watched him on film, and who actually had a vested interest in his success.
Even the criticism of the play Sunday betrays the sad truth about JP. The problem with the call, so many people (including yourself, if I don't mistake myself) say, is that it was wrong to put the game in his hands. In the hands of a 5-year veteran who should have learned something by now. A more crushing indictment of JP as a QB is hard to find.
I also agree he seems like a very nice kid. I wanted him to succeed, and would be pleasantly surprised if he did someday. But I just do not see that happening.
