The local press occasionally referred to the game as The Battle of Missouri, The Show-Me State Showdown, or the I-70 Series.

The series ended once again after the Rams returned to Los Angeles in 2016, leaving the Chiefs as the only NFL team in Missouri for a second time.

The Chiefs posted a 16–7–2 mark in its Governor's Cup series against the Cardinals from 1968 to 1987, going 3–1–1 in the regular season record and 13–6–1 in preseason play.

In often meaningless preseason games, the Chiefs and Rams gave all their energy to secure the Governor's Cup, their spot as the best offense in the league, and bragging rights for their respective city in Missouri.

Chiefs owner Clark Hunt helped engineer the Rams' return to Los Angeles, their home from 1946–94, in January 2016, when he was the sole dissenting vote for a proposal which would have allowed the Raiders and Chargers to move to a new stadium in Carson.
