Take a neutral fan flipping on a division game in December: the Eagles are the team with the target on their back, and the others are still chasing matchups. Sure, the other side can point to Washington's surge or Dallas's talent, and those are fair. But "rule" means sustained control, not one good stretch. Philadelphia has the roster, the recent division results, and the championship standard everyone else is measuring against. I'm not certain it lasts forever, but right now the NFC East runs through Philadelphia.
