I don't think people are paying attention here.
There are currently eight teams that have 4 or less losses.
Only two of them are currently on the outside looking in. To make this quick let's start with those two teams.
Seattle and San Francisco. First, these two teams play each other twice. So at least one of these teams will be worse that 12-4 if not both of them. Seattle also plays Philadelphia. So let's assume Seattle wins out, you already have to bring Philadelphia down to 4 games.
Before we go to Philly, let's look at Arizona, who Seattle also plays. Seattle to maintain that 4 games would have to beat Arizona, who would drop to 3 games. Arizona also plays San Fran, who we have in turn confirmed can't be 12-4 if Seattle is.
Now let's look at Philly. We have Philly losing to Seattle in order for Seattle to be 12-4. Now Philly can not lose another game, but they have the Cowboys twice, who also can't lose more than once in order to finish 12-4.
The reality is that an 11-5 team may miss the playoffs, but a 12-4 team will not. And that isn't at all new, but even then 11-5 stands a good chance to make the playoffs given the canabolism taking place at the end of the year.
What's more is you have a lot of NFC South divisional games remaining, and thus also making it difficult for a team to make the playoffs at 5-11. Probably 6 and 10 or 7 and 9 at the lowest.
