What would happen if the giants, eagles and cowboys all ended with 10-6?

uming the packers dont have a meltdown and HYPOTHETICALLY the cowboys beat the saints and win out the rest of the season. also, the giants win their last 3 games and somehow, the eagles win 2/3 of their games (their loss being the cowboys). they all sweep each other and there are 2 playoff spots and 3 teams tied. and uming that the skins loose to both of the giants and cowboys in the next 2 weeks and all are 4-2 in the division. who wins the division and who takes the wild card?
