Even if the Rams win out, if they end up in a 3 way tie with any of the 3 other division leaders - Vikings, Saints and Eagles, the best they can do is #2 seed and that's if the Eagles drop 1 more game and the 3 way tie is between Vikings and Saints. What really sucks is if the Rams, Saints and Eagles all finish 13 - 3, meaning the Rams have beat both of them, the Rams still end up the 4th seed behind both of them.
