I'm thinking of starting a new historical league and have used the gambo-spritze roster, but can't figure out how to re-segregate the Negro League players into a league of their own. Is there some obvious way to find the NL players that I'm missing? I don't know enough of the names to do this easily. Sorry if there's some obvious answer I've missed but searches in the forum haven't really helped.
