We have 2 Leagues : the Pre-Season and the Regular Season
We have 66 players at all

Under the PLAYER LIST, all the players were check one by one, as playing in the "Pre-Season League"

The Pre-Season League as just ended.
I will have to go through the entire PLAYER LIST and uncheck under League, all the players from the Pre-Season League and make a check on the "Regular Season"

Is there a faster way to do that without having to "uncheck and check" each player one by one??

Don't uncheck. You can go into each and add new league.

It's not necessary though to have players assigned to leagues.

I think it is important to identify the League (if more than one) were the players will play because when doing the lineup, you will have to re-create the rooster from the PLAYER LIST for each team....

I had a problem with this issue and I had to ask the forum...

Perhaps I am missing something here...

You will probably only create a roster one time (plus maybe occasionally add or remove or inactivate a player).

There is minimal value in adding players to leagues, at least compared to games (most important) and teams (less important). It can help with list management.

I definitely feel like you arent quite grasping the concept, and i'm not certain how to best explain it.

with that said, I would say unless you have a compelling reason to add the players to leagues, to not worry about it. when you are working with players, just make sure all leagues are selected and you will see everything.

I like your last remark : I will select all leagues
thanks
