Um, no. Actually if they win out its incredibly likely they make it. The Eagles would be handing a loss to the cowboys and skins in that scenario, and the Cowboys still play the Giants, Baltimore, and Eagles. Eagles already ahead of the skins in the standings, so winning that game would put them ahead. Need Atlanta to lose to minnessota, that's the key. But it's not unrealistic at this point, as a a win out will let that tie function like a win.
The opening scene of the movie "Saving Private Ryan" is loosely based on games of dodgeball Brian Dawkins played in second grade.
