There is nothing left for the Saints to prove to anyone.
We know who the Saints are. Their talent is legitimate, and they can beat any team in the NFL at any venue. The defense is that good, and the offense should, at some point, be good enough. Drew Brees was in his first game back in four weeks coming off eleven broken ribs and a punctured lung, throwing passes to practice squad players, and New Orleans was a fumble recovery away from dropping the Kansas City Chiefs.
Instead, the fumble bounced back out of the end zone, New Orleans got two points instead of seven and lost the game, 32-29.
Perhaps that's too simplistic.
No, it definitely is.
Something else would have happened, and the Saints probably would have lost the game anyway since they were never in control in this one. But at this point, the win or loss doesn't really matter, which is weird to say, but if you accept that last week's loss to the Eagles already put the NFC's No. 1 seed out of reach, then you can focus more on the process than the results.
That isn't spin. That isn't looking at the bright side. That's simply analyzing the situation and being realistic about what has already happened and what needs to happen moving forward. If you do that, there are reasons to be higher on this team than ever, depending on how optimistic you are about the things that aren't yet right.
