I inserted some games... when I got to the lineups I realized that the league setting was filtering the teams and players. This is right, but the only way I found to fix it was to delete the games, change the league setup, and add new games. Wouldn't it be easier to have league selection in the game setup? So when you create the game it could inherit the default from the league management, but you could change it from within the game.
Another idea is that maybe, at least on tablets, the screen real estate could be more exploited, by adding the league selection directly on the player, team and game screens. On my Android tablet this isn't so... I don't remember if the iPad version had this. It would save some taps.

Also... I think that the selected leagues are so important for the other things you want to do with iScore, that on tablets maybe it could be promoted to the main app screen... so you always see what you are working with.
Just my 2 cents... I still have to get used to this.
