Did you not say that a team was elite if they consistently made the divisional round? (Final 4 of your conference) You get there with a bye, or with 1 WC playoff win. Any team that doesn't win a Super Bowl proves that they are not on the same level as teams that do win the Super Bowl.
If you are just examining 1 season in 2010, how can NE be elite like GB when NE was 1 and done in the playoffs and GB won a Super Bowl? We have a much longer time frame to judge Atl, and since they have been consistently in the playoffs, I would call them one of the better NFC team, but not elite.
