The Falcs lost because they were unprepared for the wind. Part of it was how it disrupted Vick's passing, but more so because of the putrid, horrid special teams play. Kickoffs were below average, and the punting was abysmal.
Hard to be a running team when your special teams gives horrible field position.
Also, the Eagles that showed up on Sunday will get CREAMED by the Pats. Did McNabb complete a single pass to his outside receivers? For all the talk about how Vick doesn't throw to the outside, I didn't see McNabb do too much of it yesterday.
