I guess we'll find out soon enough
After the success of Bulger, Maddox, Pennington, etc. this year, who can say that Detmer won't step in and be as good as McNabb? I realize that it's expecting alot of the guy but stranger things have happened this year (and are still happening on a weekly basis).
Each team carves out its own destiny, and the Eagles are still very much alive and kicking.
