The only thing is, according to DVOA, the pass defenses we've faced in the last 6 games have been:
NO - 6th
SF - 10th
NYG - 8th
ARI - 5th
STL - 15th
NO - 6th
And looking directly at the SF game, NYG game, ARI game and 2nd NO game, I have the following comments:
Against SF it looked as if we shut up shop almost immediately and played conservatively because SF were headhunting, the last thing we wanted was to suffer injuries.
Against NYG we never ever looked like giving up points, so again we played conservatively and didn't risk throwing the game away with INTs or fumbles or getting anyone injured
Against ARI they played an absolute stonker of a game on defense, and again we also dominated on defense to the extent it didn't look like ARI would score unless we gave it to them (and if you consider that 2 of their FG drives were extended due to 2 personal fouls and a dodgy PI call, and their TD drive was extended on an 3rd down incompletion thanks to a holding call, AND the interception that never was at the end, the perfect storm occured for Arizona to take that win).
Again, against NO, we went up by 16 and never really looked like conceding 16 points, so again went conservative.
If we need to ball out, we can - we just haven't had to for a long time
