This year's Super Bowl features a rare matchup of the NFL’s top two teams from the regular season. The Philadelphia Eagles and Kansas City Chiefs were the league's only 14-game winners, marking just the sixth time since the 1970 merger that the squads with sole possession of the two best records in the regular season met for the championship. The last time it happened came after the 2013 season when Seattle beat Denver 43-8 in a matchup of 13-win teams.
