The Dallas Texans/Chiefs dominated the Broncos in the 1960s, the decade of the AFL, winning 19 of 20 games. The Broncos have responded since then, winning the series of every subsequent decade and holding a 8–2 edge so far in the 2010s. Since the Texans moved to Kansas City and became the Chiefs, Denver holds a 53–50 edge. Dallas swept all 6 meetings in the first three years of the rivalry.
October 4, 1992: The Chiefs were victimized by 8 of John Elway's 46 fourth quarter comebacks/game-winning drives, the most he had against one NFL team. Perhaps the most memorable comeback occurred on October 4, 1992, at Mile High Stadium. The Broncos trailed 19–6 late in the fourth quarter, and had not scored a touchdown in the previous 12 quarters. After the 2-minute warning, Elway threw a 25-yard touchdown pass to wide receiver Mark Jackson to narrow the gap to 19–13 with 1:55 left. After the Chiefs subsequently went three-and-out, the Broncos returned a punt to the Chiefs' 27-yard line. Three plays later, Elway threw a 12-yard touchdown pass to wide receiver Vance Johnson with 38 seconds left for a thrilling 20–19 comeback win.
December 27, 1992: Less than three months after John Elway stunned the Chiefs with the aforementioned comeback win, the Chiefs exacted revenge on the Broncos at Arrowhead Stadium in the 1992 regular season finale, with a playoff berth on the line. The Chiefs routed the Broncos 42–20, with the Chiefs' defense scoring three touchdowns off Broncos' turnovers, and denying the Broncos a playoff berth in the process.
October 17, 1994: John Elway and Joe Montana, two of the greatest quarterbacks in NFL history, squared off in one of the greatest games in Monday Night Football history. Montana played the last two years of his 16-year NFL career with the Chiefs (1993–94), after playing the majority of his career with the San Francisco 49ers (1979–1992). The two teams matched each other score for score through the first three quarters, until Chiefs' kicker Lin Elliott nailed a 19-yard field goal to give the Chiefs a 24–21 lead with four minutes remaining in the fourth quarter. After Broncos' tight end Shannon Sharpe and Chiefs' running back Marcus Allen traded fumbles over the next two possessions, Elway led the Broncos on a 6-play, 39-yard drive, and scored a 4-yard touchdown on a quarterback draw to give the Broncos a 28–24 lead with 1:29 remaining. However, the Chiefs would one-up the Broncos, with Montana connecting on a 5-yard touchdown pass to wide receiver Willie Davis with only eight seconds remaining to give the Chiefs a thrilling 31–28 win. It not only gave Chiefs' head coachMarty Schottenheimer his first victory in Denver in eight tries, but the Chiefs also snapped an 11-game losing streak at Mile High Stadium.
November 16, 1997: The Broncos were trailing the Chiefs 21–19 at Arrowhead Stadium, and were backed up at their own 27-yard line with two minutes remaining in the fourth quarter. John Elway led the Broncos down the field, with Jason Elam kicking a 34-yard field goal with only a minute left to give the Broncos a 22–21 lead. However, Chiefs' quarterbackRich Gannon drove the Chiefs to the Broncos' 37-yard line, and kicker Pete Stoyanovich hit a 54-yard field goal as time expired to give the Chiefs a 24–22 win.
January 4, 1998: Less than two months after the aforementioned last-second win by the Chiefs, the Broncos returned to Kansas City for the divisional round of the 1997–98 NFL playoffs, and redeemed themselves by upending the No. 1 seed Chiefs 14–10, en route to their first Super Bowl win that season.
October 5, 2003: Chiefs' return specialist Dante Hall returned a punt 93 yards for a touchdown in the fourth quarter, after it seemed that the Broncos' special teams had him corralled for a loss deep in Chiefs' territory. This gave the Chiefs a 24–23 win over the Broncos at Arrowhead Stadium.
November 14, 2010: The Broncos stormed out to a 35–0 lead against the visiting Chiefs before the second half, leading to a 49–29 victory. Chiefs' head coachTodd Haley was distraught after the game and snubbed a postgame handshake with Broncos' head coachJosh McDaniels, thinking that the Broncos were running up the score on the Chiefs.
