Our DTs were shut down by arguably the best pair of OGs in the entire league. Nicks and Evans were both Pro Bowlers last year I believe. It doesn't really matter how well Kreutz did or didn't play when he's got OGs of that size and talent covering for him. I think it's fair to assume our DTs aren't going to face two OGs of that caliber every week so I'm hoping yesterday was an aberration as far as that goes.
So yeah, that was probably going to happen but then Peppers and Izzy needed to pick it up on the outside and that really didn't happen either. End result, too much time for Brees resulting in his big and fast WRs getting a major advantage over our depleted secondary. That big TE of theirs (Graham) did damage as well.
I was just realizing this morning... all these things we're anguishing over today are the exact same things the Falcons fans must have been saying this time last week. Terrible OL play, QB beat to hell, questionable playcalling, ineffective pass game, sloppy D, etc. The Falcons fans thought they had the better team last week and we spanked them. We thought the same thing going into this game, and got shown otherwise.
