I think another point to consider is that Brady and Bulger were replacing Bledsoe and Warner, both pure passers, so you knew right off the bat that there would be 0 dropoff as far as mobility is concerned. With McNabb, his mobility is half his game (and, at times, over half the Eagle's offense) so not only do you have to look at the dropoff in pass accuracy, but also the irreplaceable speed and mobility they now lose. It all adds up to not a pretty picture for the Eagles. I wouldn't count them out, though, they have a good enough D that they should still be in every game.
