I've always liked Fitzy, but I've been one of those that looked at him as a career backup. I think he has some good tools, but I've thought like others that his accuracy and velocity were the biggest issues for him. Like Kelly said, there are throws that he has to make, but missed either because of accuracy or a lack of velocity on the ball.
I'm starting to wonder just how much of an issue that has to be, though. If a guy can throw for that many yards and TDs on the road against the #3 defense in the league, he's got some balls. The thing I like about him is that he has the two things that are hard to teach -- pocket presence, and the moxie to take chances instead of playing it safe. JP had horrible pocket presence, but he did have some moxie. Trent had fairly horrible pocket presence and absolutely no moxie.
It's just nice to see a guy who knows when to tuck and run, and who doesn't bail on every play if the #1 receiver isn't wide open.
Personally, I'd give the job to Fitz and do everything in my power to shore up the defense next year. The offense is actually fairly decent -- it's that defense that is downright embarrassing.
