With Brown gone, halfback Leroy Kelly became the team's primary rusher in 1966. Kelly, an eighth-round draft choice who saw limited playing time in two years as a backup, ably filled his predecessor's shoes. Cleveland missed the playoffs in 1966, but made it to the postseason the following year after a realignment of the NFL's divisions that placed the Browns in the new Century Division. The Browns, however, lost the 1967 eastern conference championship to the Dallas Cowboys. After a year in which he made just 11 of 23 field goal attempts, placekicker Lou Groza, the last remaining player from the inaugural 1946 Browns team, retired before the start of the 1968 season. Groza, who had been on the roster for 21 seasons and was 44 years old when he hung up his spikes, said in his memoir that retiring was "the saddest day of my football life."
