Okay.... so Yahoo Support was able to change it back to "Daily - Tomorrow". What that means is each day you can change your lineup before the players' games start. But for adds and drops, they don't take effect until the next day.
This way we can deal with mid-week injuries. Also, the weekly lineup deadline was usually on Sunday night so for those who forgot untiil Monday morning, they got locked into a bad lineup for the week. This gives us more flexibility.
For those who don't want to manage your team as much, just set all 7 days in advance and leave it alone the whole week... that's usually what I do unless there is an injury or I pick someone up off of free agency.
Good luck... our first week starts tomorrow... Flop City's lineup looks good.
