I think it should be after the first game, or after a player has been on the roster for a week (monday-monday), whatever comes first. It is nice to get a heads up if a player you did not expect to make it suddenly gets a spot, or some minor country backup player gets picked up as their most important player. Perhaps you want to see the games or even give the player in question some training. But as it is now, flooding the division news, I agree it is too much information (un-useful information that is).
