John Harbaugh should be everyone’s new favorite N.F.L. coach. With a smile, he proved that there is still room for subterfuge in this age of the all-seeing internet and all-knowing social media.

Moreover, we are better for it. Let it be a reminder that until the opening kickoff of that first full day of N.F.L. games, there is so much that fans, and writers, do not know about the 32 teams.

Take Harbaugh’s Baltimore Ravens.

If there is one thing we thought we knew about the Ravens it was this: Their second-year quarterback, Lamar Jackson, was going to run the football so often he would threaten single-season rushing records for a quarterback.
