It has been eight years since the Broncos were able to defeat their hated rivals in Kansas City and though that doesn't seem like a long time on the surface, it likely seems like decades for those in Broncos Country.
In the ever-changing world we live in, several things are different from that day, September 17, 2015, the last time the Broncos were able to beat the Chiefs. In many ways, it's a completely different world.
You are about to see a list of things that have changed since that day. From world leaders, to pop culture, to social media, as well as a look at other major sports. There were many things that you now use on a daily basis that weren't even a thought in 2015. Take a look.
We'll start with the football aspect of things. When the Broncos beat the Chiefs in Week 2 of the 2015 season by a score of 31-24 in a game played at Arrowhead Stadium, these were some of the players on the roster.
QB Peyton Manning
RB Ronnie Hillman
WR Demaryius Thomas
WR Emmanuel Sanders
LB DeMarcus Ware
LB Von Miller
That's just to name a few. Obviously, none of those guys are still on the team and only one (Miller) is still playing in the league. Manning and Ware are now in the Pro Football Hall of Fame and sadly, both Thomas and Hillman have since passed on.
Gary Kubiak was the team's head coach.
The world of sports
The Golden State Warriors went to the NBA finals five straight times starting in 2015, but just three months before the Broncos' last win over the Chiefs, they won their first title since 1975. They became a dynasty, but they were still a rising team at this point.
In addition, Kobe Bryant, Tim Duncan and Kevin Garnett were all still playing in the league.
The Kansas City Royals won the World Series. Also, in perhaps the biggest sports moment of the 2015 year, American Pharoah became the first racehorse to win the Triple Crown since 1978.
And one other tidbit. Patrick Mahomes, the quarterback who has never lost to the Broncos, was just a sophomore in college at Texas Tech, hardly even on the NFL radar.
The sports world lost Moses Malone, Darryl Dawkins, Yogi Berra, 'Rowdy' Roddy Piper, Dusty Rhodes, Frank Gifford and Ernie Banks.
Pop Culture
This is perhaps the most fun list to look at, because it either provides good laughs and fun memories, or it makes you feel really old.
The No. 1 song on billboard charts on this date in 2015 was "What do you mean"? by Justin Bieber. The top movies in theaters were The Perfect Guy and Maze Runner: The Search Trials. Remember those? Me either.
The best smartphone that you could buy was the Iphone 5. Yes, really. Popular pieces of pop culture such as the mega-popular video game Fortnite and the social media app TikTok did not even exist.
Empire was one of the most popular shows on network television but streaming apps such as Netflix and Hulu were continuing their rise. Fans were also still talking about the death of Jon Snow in the season 5 finale of Game of Thrones which aired just months before this particular Broncos-Chiefs clash.
The year 2015 was also the year that had millions of people asking if the dress was white and gold or black and blue. If you don't remember that, Google it.
The world lost Leonard Nimoy, Natalie Cole, B.B. King, Scott Wieland and Wes Craven.
Also, kids who are currently seniors in high school were just getting settled into their fourth-grade classes.
The world in 2015
Joe Biden was still the country's Vice President and Donald Trump had just recently announced his candidacy. Barack Obama was still serving as the President of the United States.
The rest of the major stories in world news at the time were fairly negative, including former New England Patriots tight end Aaron Hernandez being convicted of murder and sentenced to life in prison. That list could go on and on, but you get the point.
It's troubling that all of these things have happened more recently than the Broncos have beaten the Chiefs. As for the Broncos, 12 different quarterbacks have started at least one game for the team. The team has had six head coaches face and lose to that Chiefs team. The team was under different ownership the last time it beat the Chiefs.
So many things have changed but the losing to this Chiefs team has remained the same. Is this Sunday the day it finally comes to an end?
