Sharing time with another great passer, Cecil Isbell, Herber led the Packers to the title game again in 1938 and 1939. In the 1938 championship game, Green Bay lost to the New York Giants 23–17 at the Polo Grounds despite another touchdown pass from Herber. In 1939, Green Bay avenged that loss with a 27–0 drubbing of the Giants in Milwaukee. Herber threw for another touchdown in the 1939 title game. In 1940, Isbell began to get more playing time and Herber was waived at the end of training camp in 1941, and retired after 11 seasons with Green Bay.
