I'm not even an Eagles fan, and I haven't given up on them yet. So, you definitely can't bail out on them yet.
From looking at the latest standings, I'd say the Eagles have a better chance of winning their NFC East Division, than getting an NFC wildcard spot.
If the Cowboys start a losing streak, then the Eagles are sittin pretty.
If the Eagles want a wildcard spot, then best they finish up 11 and 5.
10 and 6 might be good enough for 2nd NFC wildcard spot, but I bet 9 and 7 won't cut it.
9 teams in the NFC currently have a better record than the Eagles. Assume 4 of those 9 will be NFC division winners.
If Dallas wins the NFC East, then that leaves the Eagles battling 5 other teams for 2 NFC wildcard spots.
Tighten up Eagles.
Edit: Actually, 10 NFC teams currently have a better record than the Eagles.
