His own team tried to mutiny instead of play with him.
Many Dodgers initially rebelled against the prospect of playing on the same side as a black man. However, their Hall of Fame manager Leo Durocher silenced them by vouching for Robinson's talent and claiming "he could make them all rich" by getting them to the World Series. Durocher also opined that he "did not care if the guy is yellow or black, or if he has stripes like a fuckin' zebra. I'm the manager of this team, and I say he plays."
Eventually, the Dodgers came to Jackie's defense when witnessing his treatment by fans and other players. Durocher concluded his thoughts on Robinson with reflective wisdom "this guy didn't just come to play, he came to beat ya, he came to stuff the goddamn bat right up your ass."
