ENGLEWOOD, Colo. -- The Broncos' all-time record in 54 years of playing the Chiefs is 52-56.
Seems pretty balanced... until you look at how the head-to-head series started.
Things went poorly early on for the Broncos, with the Chiefs winning the first eight games, including the first six when they were still the Dallas Texans.
And it got worse.
From the inaugural matchup on the eve of Halloween in 1960 until October 7, 1973, the Broncos beat the Texans/Chiefs just twice in 27 tries: A 33-27 win in 1964 at Bears Stadium in Denver, and a 26-13 win in 1970 in the second game at Mile High Stadium.
Considering their 2-25 start -- with the 25 losses coming by an average of 19.6 points per game -- the Broncos' steady climb back to a near-.500 record is quite impressive, especially considering half of the games have been played in one of the league's tougher road environments. After losing their first 14 road games against the Chiefs (in Dallas and Kansas City), the Broncos have gone 17-22 at Arrowhead Stadium since.
Relive the Broncos' series history with the Chiefs with photographs dating to the teams' AFL roots in the 1960s.
Overall, Denver's 50-31 run since giving Kansas City a 23-game head start includes the sort of strong stretches you'd expect to climb out of such a deep hole: There was an eight-game win streak from 1976 to '79, a 12-of-15 stretch from '85 to '92 and the active five-game win streak that began with Peyton Manning's arrival in Denver.
Manning himself has a streaky history against the Chiefs, albeit more one-sided. Before joining the Broncos, he faced off with Kansas City eight times, including two playoff games, and lost just once: a 45-35 defeat at Arrowhead Stadium on Halloween in 2004.
But the successful stretches Manning and the Broncos have posted against the Chiefs belie just how hard-fought most of those games have been. Of Manning's seven wins over KC with the Colts, four have been decided by just one score. Since No. 18 joined the Broncos, Denver's five-game win streak hasn't exactly been filled with blowouts.
In 2012, when Kansas City finished 2-14 and was outscored by a league-high 214 points, the Broncos had to claw back from 6-0 and 9-7 deficits at Arrowhead to beat the Brady Quinn-led Chiefs 17-9. The eight-point margin of victory was the second-smallest the Broncos posted during their 11-game win streak to finish the season.
2013 brought a 27-17 Broncos win in Denver, but also a 35-28 win in Kansas City that began with the Chiefs up 21-7 early in the second quarter. In their first matchup this season, John Fox's crew came out with a W, but only after sweating out a 52-yard drive to the Broncos' 2-yard line, which ended in a fourth-down batted pass by Terrance Knighton. Now the Broncos head back to Arrowhead, where Andy Reid's team has beaten the Seahawks and Patriots by a combined 31 points and the noise level has been measured as high as 142.2 decibels, an official world record. With a win, the Broncos would pull within three games of tying the series. But for the streakiness to continue, the Broncos will have to bring their best in Kansas City.
