Brian Dawkins, long a mainstay of the Eagles defense, signed a 5-year deal with Denver today, which will cause no end of friction between me and my brother-in-law, the Broncos fan.
All that being said, I don't think this will bite the Eagles too badly, for several reasons. For one, Dawkins had notably slowed this year, and while his instincts remained impeccable, his production tailed off significantly. For another, Jim Johnson's defense did a lot to emphasize Dawkins' strengths and hide his weaknesses, something that the new scheme he'll be playing in Denver may not do. And finally, if the Eagles have depth anywhere, it's at defensive back.
So farewell, Weapon X, and thanks for the memories. Good luck in Denver - I think you're going to need it.
