Historically, as a general observation, teams that make the Superbowl, RARELY lose by double digits in any regular season game.

The last 20 teams that played in the Super Bowl had 78 combined regular season losses (2008-2017). 24 of those losses were by double digits or more.

So, 31% of regular season losses by Super Bowl teams were by double digits or more.

13 out of the 20 teams (65%) had at least one double digit regular season loss.

Not rare.
