Its highly improbable that we'd be able to get the #1 seed at this point. Even if we finish 13-3, Seattle would have to go 2-3 in its final 5 games, and they are 10-1. Do you really expect them to do that.
Winning the division would be gravy right now because its a 1st round bye and a game at home. If we don't win the division, we have road games against N.O. and Seattle in the playoffs if we are lucky enough to get by in the 1st round against NFCN winner (Lions have enough pieces to beat us in a game, Chicago and GB do not)
