By Merrill Reese: Turnovers kill.  That’s not a new theory.  It’s something we’ve known for as long as we’ve watched football.  Occasionally you overcome them against an inferior opponent but eventually they stop you in your tracks. It’s still early and the Eagles are in good shape at 3-2.

Michael Vick’s fourth quarter comebacks have been brilliant, but unless he duplicates the ball security he displayed against the Giants, there’s trouble ahead.
