I agree with this. The Falcons and Bucs would have to finish with worse records than us. We still have a game vs the Bucs but they apparently have a pretty easy overall schedule remaining.
Atlanta already has 6 wins to our 4 with only 6 games remaining. It’s not impossible - but very improbable - in my opinion.
Also as for the WC, I don’t think 10-7 guarantees a spot this season.
The Vikings and Packers are already at 9 and 8 wins, respectively.
The Commanders are at the 7 spot now with 7 wins and the NFC West is a logjam of 6-5 to 5-6 teams, all of which are ahead of the 4-7 Saints.
The Saints could conceivably run the table, winning their last 9 games and still not control their own destiny for a playoff birth.
