ie. League - register up to 15 players before the first game of the season - and during the season you can add up to 3 new names to register with your original (totalling a maximum of 18.)
I really like this idea. I might modify it a bit to the following for league play:
-15 roster spots per season; 11 have to be assigned for the first game of the season, otherwise BB assigns them for you. And if you do not have 11 players on your roster, BB automatically signs up scrubs (similar to lucky fans) to fill the void.
-Whenever you set an illegal line-up, 5 players are chosen at random from the list to play (this eliminates walkovers).
-Ability to put one player on "injury reserve" per season, provided they are injured and that it does not reduce your roster below 11. This frees up their roster spot but they cannot play in league games anymore (just cup and scrimmage when they heal), unless you have a roster spot to add them again later.
-More injured reserve spots could be added in the event that a team has a castastrophic injury problem that reduces their ability to field a line-up.
I may even reduce the number of roster spots to something like 12-13 and the minimum roster to 8-9. If you are allowed to have separate players for cup and league play, 15 spots is not really limiting.
