The defense was decent for about a quarter or so but they were still generally horrible, the only reason there isn't too much outrage is because they've been historically horrible most of the year and last night was kind of "normal horrible" for the NFL.
Even with the turnovers they couldn't get off the field on 3rd down and force a FG, including on the drive following the Dalton INT which started on like the Cardinals 35, and of course they gave up an 80-yard bomb to a QB who could barely hit the broad side of a barn.
