The double digit losses thing comes from a time, almost five years ago. If you check recent years, you will see a few blowouts per year. And EVERY playoff loss since the SB that was not a wildcard game has been a blowout.
I think we can shelve the idea that Carroll does not get blown out. He does. He does it less since we tend to start trying to run the clock out halfway through the 1st but it still happens.
What made yesterday rare was not getting blown out, but getting blown out at home by a team using a backup QB.
