Right now either the 49ers or Seahawks are going to have to go on the road and play either the Cowboys or the Eagles. Why should the Eagles or Cowboys be rewarded homefield advantage when they play in a mediocre division? Meanwhile the 49ers and Seahawks have to play each other twice, and one of them will be punished, despite the possibility that they both might be tied for the best record in the NFC or even the NFL when the season ends. I don't think a complete realignment (two teams from the same division having the #1 and #2 seed) is necessary, but there is no reason to reward a division winner with homefield advantage, just because they won their division. It might make wildcard weekend more competitive with the way it is now, but it doesnt make the playoffs more competitive having a good team have to go play back to back road games, because they played in the wrong division.
