We have to be realistic as fans.
The 2020 Denver Broncos are at least a year away from playoff contention and the 2020 Kansas City Chiefs are likely the best team in the NFL and on their way to a repeat Super Bowl championship.
On top of that, the Broncos have won only handful of games in Arrowhead during the month of December in their entire 60 year history. They are a woeful 3-18 all-time on the road in Kansas City once the calendar turns from November to December. Two of those December wins came with John Elway or Peyton Manning at quarterback.
