However, thereafter the team fell on hard times in the sixties, finishing in last place five straight seasons, during which time Bucyk — generally paired with centre Murray Oliver and winger Tommy Williams — led the team in scoring several times. When the Bruins became a powerhouse in the late Sixties, Bucyk — by then the team captain — rose with the pack, with great production including a 51-goal season in the 1970–71 season in his mid-thirties, and helping the Bruins to win two Stanley Cup titles in 1970 and 1972. Bucyk proved particularly effective playing on the left side on Boston's greatly feared power play unit, which featured Phil Esposito, John McKenzie, Bobby Orr and Fred Stanfield.
