The 1979Kansas City Chiefs season ended with a 7–9 record and fifth-place finish in the AFC West. The Chiefs missed the playoffs due to the four other teams ahead of them in their division all finishing with winning records.
With Fuller at the helm, the Chiefs owned a 4–2 record after six games, but a five-game mid-season losing stretch sullied that effort. Despite finishing fifth in the AFC West for a second straight season, Kansas City’s 7–9 record was a notable accomplishment considering the fact that the division’s other four clubs all posted winning records for a second consecutive season.
The Chiefs closed the season by dropping a 3–0 decision at Tampa Bay on December 16 in one of the most water-logged contests in franchise annals. As both clubs struggled to move the ball under monsoon-like conditions (Kansas City was held to 80 total yards), a field goal late in the fourth quarter by the Buccaneers' Neil O'Donoghue averted the NFL’s first scoreless tie since 1943, allowing Tampa Bay to win the NFC Central division championship after a three-game losing streak.
The Chiefs set a dubious NFL record for the season, with the fewest number of passing yards (1,660, 103.8 per game) in a 16-game season.
