Here is the Redskins' operative playoff scenario, it's this simple: win out and the Saints must lose one. In all other scenarios the Redskins will hold tiebreakers over teams with the same record.
The Vikings are one game ahead of the Redskins right now and the Redskins play the Vikings in two weeks. By virtue of losing to the Redskins the Vikings would then have the same record at best and the Redskins would have the head to head tiebreaker.
The Lions and Cardinals could win out and be tied with the Redskins. The Redskins beat both those teams.
If the Saints and Redskins win out the Saints will get the second wildcard by virtue of a better conference record.
Worst case scenario from here.
