Any non Head-to-Head Custom League that completes its draft after the start of the baseball season can elect to have the stats of their starting lineup made retroactive to the start of the season. The commissioner may choose to use this option during the league creation or set it at any time prior to the draft date via the Edit League Settings page. Retroactive stats always go back to the beginning of the regular season.
Once your league's draft is complete, this setting cannot be changed.
After your league has drafted, the commissioner will have the next fourteen days to select the date on which your retroactive stats will be run—there will be seven days from which to choose.
By 11:59:59 p.m. PT on the night before the retroactive stats are to be run, all teams should have set their starting lineups to contain the players they wish to receive retroactive stats for. All teams will only be given retroactive stats for one lineup, so the team that is set on this day will act as though it was active for the entire season.
Once the retroactive stats have been run, they will not be rerun or cleared. All managers need to have their lineups set before the chosen date.
Once the retroactive stats have been run, the league will begin to function like any other.
If the commissioner does not set a retroactive stat date within the fourteen-day window, the league will begin to receive stats on the following (fifteenth) day—without any retroactive stats.
