This feature allows you to specify certain criteria, based on how fatigued your starting goalie is, to have the system automatically swap the starter for one of your backups between games. This is particularly useful when you are out of town or cannot manage your team for a period of time.
Game are played between 2:20 AM/PM ET and 3:00 AM/PM ET each day. The automatic swapping, if turned on, will occur between 3:45 AM/PM ET and 4:15 AM/PM ET, or roughly one hour after each game is played.
