The 1973 Kansas City Chiefs season ended with a 7–5–2 record and third-place finish in the AFC West. For 1973, the defense kept the club in contention thanks to a nucleus that still included the bulk of the squad’s Super Bowl IV starters. Quarterback Mike Livingston started in a 23–13 Opening Day loss against the Los Angeles Rams on September 16, but Len Dawson returned to rally the club for three consecutive wins to get the club off to a 3–1 start for a third consecutive year. The aging Len Dawson made his final start of the year in a 23–14 loss at Buffalo on October 29 and was replaced for the remainder of the year by Livingston, beginning a string of three straight seasons in which both players split time at the position.
