I know I just posted a chart from 1974, but this year is illustrative to compare the first class with 1976. The first 5 plots are the original class. The last 4 (furthest t the right) are 1976, the strongest class since the first one.
I made a very swaggy comment some time back that players with composite scores of 10 or above are once in a decade players. With 97 seasons played, the Hall has 9 players that have a composite score of 10 or better. I like it when I swag on target.
