Losing 'Edge' will be tough on the Colts and resigning Reggie Wayne isn't even a done deal. Steelers will be tough, but so will New England, Denver and Cincinnati. San Diego and Jacksonville won't be pushovers either.
And for all the whiny Seahawk fans out there, you've got a good team... a very good team. I can't help but think they will be the NFC frontrunner next year along with Carolina and perhaps Dallas if they can get their act together. Sorry Bears, try playing a first place schedule and see how far you go. Although they could win their division by default.
It's hard to make a prediction until training camp.
