If you actually read the article no one was defending the poor offensive production or poor play on Flacco's part. The FACTS are that they did enough in quite a few of the losses to put the team in a position to win and the D choked. Just FACTS, no rationalizations or excuses. Other teams in our division had issues at some point last year as well and it's likely if the D had not choked in just a couple of those losses the Ravens are in the playoffs.
I'm not going to bother going into the "exhausted D" argument, that's been discussed ad nauseum and is not even close to being right. And if you watch football at all you will see that more often than not it comes down "to one stop at the end of the game" all over the NFL, week in and week out. Rarely are there "comfortable wins" any more.
Again, I don't see anyone saying that huge improvements aren't needed on offense, Stevie Wonder could see that. But none of that matters if you don't finish games. Look no farther than the this year's SB for a perfect illustration of that FACT.
