OK,
I've finally completed a valid 100M Immaculate Grid roster. I think it has enough innings pitched and plate appearances and might even be halfway competitive.
After the effort involved, I am even more determined to play this team somewhere. If I don't make the cage I hope we go ahead with the consolation round idea. And if not, I will create my own theme league to play this.
So I would recommend anyone on the fence about waiting to begin this theme to start playing around with some different combinations. It's not easy, but is certainly a great and fun challenge.
And, for the few of you not already familiar with it, or who are baseball savants,, I strongly suggest using this link to assist:
