Cincinnati Reds (1972-1978)
The Big Red Machine had three future Hall of Fame hitters in their prime. Pete Rose hit leadoff and was in the top 10 in batting average every year in the league. While these three played together he finished first in hits three times and second three times as well.
Joe Morgan could pretty much do it all. He hit for average, power and could steal bases as well. He was a perfect fit for second or third in the lineup.
And Johnny Bench usually batted clean-up. He led the National League with 40 home runs in 1972 and was consistently in the top 10 in RBIs and slugging percentage.
The trio went to three World Series and won back-to-back titles in 1975-76. The Reds' offense during those two championship seasons was leaps and bounds above any other team in the National League. In 1975 they averaged 5.19 runs per game and the second best team averaged 4.54.
Each member of this trio won the NL MVP. Bench won it in 1972, Rose won his the following year, and Morgan won back-to-back MVPs in 1975-76.
