–it is not all that uncommon for teams to have multiple Hall of Famers on them and not win. The
Pirates from 1932 through 1935 had four or five Hall of Famers on the team every year and did not win. After winning a pennant in 1962 (and losing the World Series), from 1963 through 1966, the Giants had five Hall of Famers each year and did not win. The White Sox from 1933 through 1935 had three Hall of Famers and did not finish above .500 in any of those years. The New York Giants between 1927 and 1932 had 5 or 6 Hall of Famers on the team each year, but didn’t win (they did win in 1933 when they had 4, one of whom was not playing regularly). You could find other examples.
