The Hall of Merit, and it's
Plaque Room.
Of the 38 players you listed, 22 of them have been elected to the Hall of Merit, with the odd men out beind Brian Downing, Fred McGriff (not yet eligible), Norm Cash, Bert Campaneris, Tony Fernandez, Jose Cruz, Frank Howard, Willie Davis, Vada Pinson, Cesar Cedeno, Rusty Staub, Dave Parker, and the non-Blyleven pitchers. Since the HoM isn't a straight career ranking (although it has some pure career voters, and on the flipside, some pure peak voters), which is what you're using, that likely explains the differences.
Just curious, why did you include Fred McGriff but not Barry Larkin and Roberto Alomar?
