We are in the middle of importing a league form ESPN of 10 teams and all players. Problem is taht you have to import all teams and all players before you can save. Roster importing is a tedious and lengthy process. if a browser crashes, then none of the changes have been saved yet. one feature to desire is to allow the commish to save the current status of the rosters. It would make sense to mark the league as not active to prevent play with partial rosters.
