Oakland and the AFL, when he said, "... the AFL is becoming much more sophisticated on offense. I think the league has always had good personnel, but the blocks were subtler and better conceived in this game." The AFL added its tenth and final team on May 24, 1967, when it awarded the league's second expansion franchise to an ownership group from Cincinnati, Ohio, headed by NFL legend Paul Brown. Although Brown had intended to join the NFL, he agreed to join the AFL when he learned that his team would be included in the NFL once the merger was completed. The Cincinnati Bengals began play in the 1968 season, finishing last in the Western Division. Legitimacy and the end of an era (1968–1970) While many AFL players and observers believed their league was the equal of the NFL, their first two Super Bowl performances did nothing to prove it.

Led by their stalwart defense—which allowed a record-low 144 points—the 1968 Colts were considered one of the best-ever NFL teams. By contrast, the Jets had allowed 280 points, the highest total for any division winner in the two leagues. They had also only narrowly beaten the favored Oakland Raiders 27–23 in the AFL championship game. Jets quarterback Joe Namath recalled that in the days leading up to the game, he grew increasingly angry when told New York had no chance to beat Baltimore. Three days before the game, a frustrated Namath responded to a heckler at the Touchdown Club in Miami by declaring, "We're going to win Sunday, I'll guarantee you." Namath and the Jets made good on his guarantee as they held the Colts scoreless until late in the fourth quarter. The Jets won, 16–7, in what is considered one of the greatest
