Well, this particular example is now academic, the Redskins having lost to Dallas in
classic Redskins style, by piling missed opportunity, upon missed opportunity, upon missed opportunity....
But ...
I think the difference the standings use is that they are tied for first in their division while the Redskins are in third
That's because in the competition for
their division championship, they are ranked only against the other teams in their division...
If a 6-3-1 team and a 6-4 were in the same division, the 6-3-1 team would be ranked above them...
If you rank all the teams in the Conference by their record (which was my point) three of the top four (the exception being the Sea Hawks) were in the NFC East at the time I posted that, and my claim was correct. (Of course if I made the same claim
now, I'd be wrong...

)
This is important and has real meaning, because in competition for the Wild Card spot, (where the records are compared across the whole Conference, not just within the division) a team that finishes 11-4-1 is going to beat-out a team that finishes 11-5, because they have the the higher winning pct.
As a result of Thursday's unhappy events, the Redskins have now dropped to 6th place in the Conference with a .591 winning pct...
Behind the Lions, (7-4, .636) and the Falcons (6-4, .600) but still ahead of the Vikings (6-5 .545)
