Read this excerpt from I Never Had It Made. Winning his directors' approval was almost insignificant in contrast to the task which now lay ahead of the Dodger president. He made certain that word of his plans did not leak out, particularly to the press. Next, he had to find the ideal player for his project, which came to be called "Rickey's noble experiment." This player had to be one who could take abuse, name-calling, rejection by fans and sportswriters and by fellow players not only on opposing teams but on his own. He had to be able to stand up in the face of merciless persecution and not retaliate.

On the other hand, he had to be a contradiction in human terms; he still had to have spirit. He could not be an Uncle Tom. His ability to turn the other cheek had to be predicated on his determination to gain acceptance. Once having proven his ability as player, teammate, and man, he had to be able to cast off humbleness and stand up as a full-fledged participant whose triumph did not carry the poison of bitterness.
