New Jersey did not come to pass. (Seven Super Bowls - XVI in Pontiac, XXVI and LII in Minneapolis, XXVIII and XXXIV in Atlanta, XL in Detroit and XLVI in Indianapolis - have had colder outdoor temperatures but were played fixed-roof stadiums, except XLVI at the retractable-roofed Lucas Oil Stadium.) The change of venue meant this was not only the last of three Super Bowls played at Tulane Stadium, but the last professional game played in the stadium, which was demolished five years later and replaced for the 1975 NFL season by the Louisiana Superdome, which has hosted every Super Bowl held in New Orleans since. The circumstances surrounding Super Bowl IX prompted the NFL to adopt a rule prohibiting a new stadium from hosting the Super Bowl following its first regular season.

At the end of the show, Mary Tyler Moore announced the following over the credits: "If the Pittsburgh Steelers win the actual Super Bowl tomorrow, we want to apologize to the Pittsburgh team and their fans for this purely fictional story. If on the other hand, they lose, remember, you heard it here first." And, as it turned out,
