Actually we weren't that bad on defense, and anyone scratching their heads about the defense against the Ravens wasn't watching the game.
We were terrible on offense, but we weren't -that- bad on defense. Aside from the blown first play of the game (83 yard TD), Rice had 3.6 YPC, McGahee 3.1 YPC. Aside from the 24 point first quarter, the Ravens didn't do much of anything, and let's recap how that first quarter went...
Drive 1:
------------
1st play of game, 83 yard TD run... OK that was terrible, but give it a mulligan
Drive 2:
-----------
Brady fumbles on 3rd play, Ravens recover at 17 yard line
Ravens score making it 14-0.
Drive 3:
------------
Pats go 3 & out
Ravens go 3 & out
Drive 4:
-------------
Brady throws INT on 4th play, Ravens end up on 25
Ravens score making it 21-0.
Drive 5:
-------------
Brady throws INT on 2nd play, Ravens run back to 9
Ravens settle for FG, 24-0.
The offense gave that game away. No defense can be expected to stop another team when given that field position (17,25,9) that quickly (3 plays, 4 plays, 2 plays) by the offense.
The offense ran a grand total of 9 non-turnover plays in 4 possessions in the 1st quarter by the time it was 24-0.
Brady was finally forced to spread the ball around to guys like Aiken, and that was the reason we lost. But then again people accuse Brady of having a "bad" year because he wasn't spreading it around to these guys...
