After the first two Super Bowls, it was widely thought that the NFL was vastly superior to what was then the AFL. In 1969, even though the NFL's Baltimore Colts were favored over the AFL's New York Jets, Quarterback Joe Namath guaranteed a Jets victory. The Jets would shock the country with a 16-7 victory over the Colts. It's widely though that this meant the AFL had arrived. It's said to have spurred on the merger that brought the AFL teams into the NFL.
Since that game was 50 years ago, CBS paid tribute to Namath in it's pregame coverage of this year's Super Bowl.
