By 1967, Cannon believed an AFL championship was imminent for the Raiders, and so fully embraced the team's game plan. He convinced Davis to sign Blanda as a placekicker and a mentor for quarterback Daryle Lamonica. That year, Cannon led all AFL tight ends with 629 yards receiving and ten touchdowns in his most productive season at the position. For the second time he was an All-AFL selection, this time as a tight end. His efforts helped the Raiders to the 1967 AFL Championship game against the Oilers and a 40–7 victory over his former team. Because of a new agreement between the two leagues, the Raiders earned a place in the second AFL–NFL World Championship game, in which they faced the Green Bay Packers. Early in the fourth quarter, Cannon dropped a pass while wide-open on a play on which he would have scored. He later described it as "the clumsiest drop of my career." Green Bay won the game, 33–14.
