Without going into excessive detail about the particulars, the way the NFL schedule works, you can know, for certain, that a given team will host another team (not in its division) once every six years.
Three years ago, I made a note that my father-in-law’s favorite team, the Detroit Lions, were due to visit the Atlanta Falcons this year.
I planned for it.
I intended to get tickets.
Then the official 2014 schedule was released, and guess which Falcons game the NFL decided to send to London?
Ugh.
