A great lineup. Had they won the WS, at least two more members would have been inducted into HOF (Williams and Santo).
The 1960s and early 1970s Cubs are one of the most talented teams who never made the post-season. Ron Santo became the third baseman in 1960, and for the remainder of the decade, the Cubs had a very stable lineup of players. Ernie Banks played two years at short next to Santo and eight years at first; Don Kessinger moved into the shortstop spot in 1965 and stayed for 11 seasons; that same year, Glenn Beckert won the second base job, which he filled through 1973; for four seasons Dick Bertell was the Cubs' starting catcher, and starting in '66 Randy Hundley enjoyed an eight-year run behind the plate, through 1973; Billy Williams was starting in the outfield every year from 1961 to 1973.
Banks (1B), Beckert (2B), Kessinger (SS), Santo (3B), Hundley (C) and Williams (LF or RF) were 75% of the team's lineup from 1966-1969. Five of those players were in the starting lineup in four other seasons (1965, 1970, 1972, 1973). In 1966 the six players played in 910 of 972 possible games at their positions. In 1967 it was 916 of 966, in 1968 it was 949 of 972, and in '69 it was 917 of 972. Thus, for four seasons, the six played in 95% of the Cubs' games.
