Philadelphia shook off a shaky start and cruised to a 26-7 victory over a banged-up Seattle Seahawks team.  Seattle scored on their first play from scrimmage on a 90-yard reception by Koren Robinson, but did not threaten the rest of the game.  Robinson beat Lito Sheppard and Brian Dawkins missed the tackle as the Seahawks jumped out to a 7-0 lead.  Donovan McNabb had another ugly start, firing incompletions on his first seven pass attempts.  However, in the second quarter, the Eagles began to move the ball and McNabb found Reggie Brown for a 22-yard touchdown.  On the next drive, with first and goal, the Eagles ran a play-action fake and McNabb threw it to offensive guard Todd Herremans (who was lined up as a tight end) for a 1-yard touchdown and a 14-7 lead.  Philadelphia's next four drives led to David Akers field goals as they sailed to a 26-7 win.  The Eagles' defense forced Seattle to punt on their final ten possessions and Darren Howard had two sacks.  McNabb finished with 349 yards passing, two touchdowns, and an interception.  Backup tight end Brent Celek had the game of his life - finishing with six catches and 131 receiving yards.. How many yards difference were there between the longest reception and the shortest?
