I don't know what football you've been watching this year, but the NFC is far from "weak".
8 of the top 15 offenses in the league are NFC teams. (1. Seattle, 7. New York, 9. St. Louis, 10. Arizona, 11. Atlanta, 12. Washington, 14. Philadelphia, 15. Dallas)
8 of the top 15 defenses in the league are NFC teams. (1. Chicago, 2. Tampa Bay, 3. Carolina, 7. Washington, 8. Green Bay, 10. Dallas, 12. Arizona, 14. Atlanta)
Hardly "weak" rankings. The NFC divisions are also alot closer and more competative than the AFC divisions are.
NFC East
New York | 10-4
Washington | 8-6
Dallas | 8-6
NFC South
Carolina | 10-4
Tampa Bay | 9-5
Atlanta | 8-6
NFC North
Chicago | 10-4
Minnesota | 8-6
All of these divisions are still up in the air. Only one NFC team (Seattle) has clinched their division, while three AFC teams (New England, Indianapolis, Cincinatti) have already clinched theirs'. The AFC may have been the better conference in 2004, but 2005 is a different story.
It's also pretty funny how you can just say "team x is better than Atlanta" without backing it up with anything. Or "if Atlanta were in the AFC, they would be under .500". Pretty stupid.
