Thanks bheid408. I want to create a theme league with only MLBers that played at one time in the Pacific Coast League and in the Negro Leagues. I am thinking of starting by requiring players to play only in the MLB rookie season, allowing us to advance one career season at a time, but with owners free to use whomever they want among that white-listed population. So a sort of non-progressive league with some of the features of a prog, but less work involved for everyone, especially, sorry, the commish, since I can't really run a progressive anytime in the near future. But a recurring theme league yes.
I am at work on the player pool. One problem is that I can't find a complete list of all MLB players that played in the PCL. Only HOFers, or the PCL award winners and all-stars, that kind of thing. If nothing else we could use that, but I would like to include less known players in the league too. Still working on it, ploughing through several books on the PCL's history and as many sites as I can find. If anyone knows where I might find a more comprehensive list, that would be great.
