In the fourth annual "Bracketology," the NFL is trying to determine which individual game is the best in the sport's deep-rooted history.
The Kansas City Chiefs, together with the Miami Dolphins, have been entered into the "Dynasty Makers" bracket as the No. 7 seed for their 1971 AFC divisional round game, a game held on Christmas Day and commonly nicknamed "the longest day."
Fans can vote for each matchup, with the game receiving the most votes within the matchup moving onto the next round. Voting for the first round runs from now until Friday, March 20.
To view the entire bracket and to vote, visit NFL.com/bracketology.
The winning game will be unveiled Sunday, April 5 with the full-game broadcast of that game airing on NFL Network that day at 7:00 PM CDT.
