Sorry, I have to disagree with the upgrade camp. Harrington might be as good a passing QB as Vick, but he is nowhere near the threat as an overall player that Vick is.
You need some decent QB play to move down the field and put your guys in a position to score. The threat of Vick opened up a lot of things for the running game, and he ran for a LOT of first downs to extend drives, enabling the RBs to therefore get more touches and produce more.
The result of a switch to Harrington from Vick should be fewer plays overall, fewer scoring opportunities, and probably more passes, as the Falcons may well be a really bad team and have to play from behind a lot. Could be OK for Norwood, he will probably get more touches, and could get some interesting garbage time stats.
