1989 Kansas City Chiefs season

The 1989 Kansas City Chiefs season ended with an 8–7–1 record and second-place finish in the AFC West. The season was the first with head coach Marty Schottenheimer and general manager Carl Peterson.

The Chiefs had changed coaches before, but never had the organization gone through the complete overhaul it did between the 1988 and 1989 seasons. On December 19, 1988, Lamar Hunt hired Carl Peterson as the team's new president/general manager. Peterson wasted no time in making changes. On January 5 he fired head coach Frank Gansz two weeks after taking over. On January 24 he hired Marty Schottenheimer, who was fired by Cleveland Browns owner Art Modell. Schottenheimer also cleaned house and with Peterson's help by making several roster changes.

The Chiefs started the season at Denver on September 10 but the Chiefs lost the opener, 34–20. The very next Sunday the Chiefs downed the Los Angeles Raiders 24–19, Schottenheimer's first win as Chiefs' head coach.

The Chiefs would start the season 1–4, but soon turned things around. On October 22, Christian Okoye carried the ball 33 times for 170 yards as the Chiefs defeated the Dallas Cowboys at Arrowhead Stadium, 36–28. During the Chiefs unexpected success, rookie linebacker Derrick Thomas made 10 sacks while Stephone Paige led the receivers with 44 receptions.

On November 26, Kansas City cruised past the Houston Oilers, 34–0 to start a 3-game winning streak to give themselves a chance to make the playoffs. Steve DeBerg passed for 2,529 yards in his second season with the team.

On December 17, using a bruising running game and a smothering defense, the San Diego Chargers marched into Arrowhead Stadium and crushed the Chiefs' playoffs dreams. They bulldozed their way to 219 yards rushing, 176 by Marion Butts, and won 20–13. The all but eliminated the Chiefs from any chance of making the playoffs. Christian Okoye constantly found his path blocked, holes jammed. Chiefs' quarterback Steve DeBerg was ineffective because of the chilling 18-degree weather and completed just 14 of 33 passes. The Chiefs had one final opportunity to tie the game, driving from their own 36 yard line to the San Diego 19. Deberg's next pass into the end zone was intercepted, ending the Chiefs' chances and the game. The loss Left the Chiefs Needing a win at Miami combined with a Pittsburgh Loss in final week to make the playoffs.

The next week, the Chiefs did bounce back and defeated the Miami Dolphins for the second time in the season, 27–24 and had their first winning record in the Schottenheimer-Peterson era. Pittsburgh however won their game and final AFC Playoff spot. Christian Okoye led the NFL in rushing with 1,480 yards. Okoye was named to the Pro Bowl along with defensive stars Derrick Thomas, Albert Lewis and Kevin Ross. This season proved to be a prelude of good things to come.
