In 1977 Eddie Murray and Andre Dawson were the Rookies of the Year. Both went on to be enshrined in Cooperstown. Its not often that both AL and NL Rookies of the Year land in the Hall of Fame.
In 1956 it was Luis Aparicio and Frank Robinson.
In 1967 we had Rod Carew and Tom Seaver.
And the most recent is Eddie Murray and Andre Dawson in 1977. The 2001 ROY's Ichiro and Albert Pujols, look like they have a pretty good chance but that is a fairly long drought.
