re: What the hell happened to this defense after being pretty good last year?

It's the players, not Rob Ryan. Same thing happened after the 1st year with Gregg Williams. I don't know if they are just not trying or don't want to or just suck. This is the same defense from last year. Hell, it's supposed to be much improved. Main reason is Patrick Robinson and the pass rush is not getting any pressure, which was a big reason for success last year. This has always been a theme with the Saints defense. They just don't get it. They have cost us too much over the years and something has got to change.
