If you and a group of your friends would like to have any easy way to see how you players stack up against each other on the leaderboards, just create a Custom League:
When you create a Custom League, anyone you add to the league will then see that league show up on their FanGraphs: The Game dashboard for easy access.
If you are added to a league that you don’t want to be a part of, you can go to the Custom League page and hide the league from your dashboard:
Custom Leagues use your already existing players and don’t impact the way the game is played at all. You can join as many or as few Custom Leagues as you like.
