When you look at the NFC, there are a few perennial contenders on the verge of 'aging out'. Packers, Saints, Bucs and possibly Dallas. Packers and Saints have major cap issues, and it's possible that neither has a ready answer at QB. Bucs are being held together with tape and Brady Magic. Cowboys will probably try to run it back one more time (Jerrah's 79, after all), but they've got cap problems, two ridiculous contracts acting as anchors, and an aging OL.
Rams and the Niners look in solid shape moving forward, but, under this scenario, teams like the Giants facing rebuilds might look pretty good in a couple of years. Just in time to take on what's certain to be...the defending Super Bowl Champion Philadelphia Iggles!
