The 1966 Green Bay Packers season was their 46th in the NFL and resulted in a 12–2 record, coached by Vince Lombardi and led by quarterback Bart Starr. The team beat the Dallas Cowboys in the 1966 NFL Championship Game, the Packers' 10th NFL title. The Packers recorded a 35–10 victory over the Kansas City Chiefs in the inaugural AFL-NFL Championship Game. Quarterback Bart Starr was named the league MVP. Said Cold Hard Football Facts about Starr's 1966 season, "Starr, always underappreciated, was at his classic assassin-like best in 1966, his lone MVP season. He led the league in completion percentage, yards per attempt and passer rating, while his 4.7-to-1 [touchdown-to-interception] ratio remains one of the very best in history. Starr, as always, cranked out great performances when he absolutely had to: the 1966 Packers, for example, were the worst rushing team in football, with a meager average of 3.5 [yards-per-attempt] on the ground, despite the reputation Lombardi's Packers still carry with them today as a dominant running team." Cold Hard Football Facts also notes that 1966 Packers had the best passer rating differential (offensive passer rating minus opponents passer rating), +56.0, in the Super Bowl Era. In 2007, the 1966 Packers were ranked as the 6th greatest Super Bowl champions on the NFL Network's documentary series America's Game: The Super Bowl Champions.
