I've been a Saints fan for 45 years.......
I agree that DA is not the answer, he's not a leader of men.
With that said, he hasn't forgotten how to coach defense. I think this loss has more to do with injuries and aging veterans.
But, I'll also say that I'm 62, and I've never seen a Saints defense quit like they did in the 2nd half of this game.
Let's hope they find an answer somewhere soon.
