Ice Bowl. The 1967 NFL championship game was one of the most famous in NFL history. It was a rematch of the title game the previous season when Green Bay won 34-27 in Dallas on the way to the first Super Bowl title. The game-time temperature was 15 degrees below zero with a wind chill of minus-48. Making matters even worse, the turf-heating system at Lambeau Field malfunctioned, turning the surface to ice. The Cowboys led late 17-14 late in regulation when Starr led from the Packers 32 to the 1. On third down with 16 seconds left and no timeouts remaining, Lombardi went for the win and Starr sneaked it in behind Jerry Kramer for the 21-17 victory.
Super Bowl III. The AFL and NFL announced a merger in 1966 to form a unified league starting in 1970. In the interim, the two champions would play in what would become known as the Super Bowl. The more established NFL won the first two title games relatively easily behind the Packers and the third one figured to be a mismatch as well between the upstart New York Jets of the AFL and the vaunted Baltimore Colts of the NFL. The Colts went into the game as 18-point favorites but Joe Namath famously "guaranteed" a New York win. The Jets dominated the game, rushing for 142 yards and forcing five turnovers to win 16-7 and establish the AFL teams as legitimate rivals to the NFL squads.
