If I am remembering correctly (which is a big if), they usually start the daily game a week or two into the season. Not sure what they're going to do this year - I think we all would prefer to start sooner rather than later.
Daily Leagues are usually made available after about 2-3 games. Whether they are doing it this year is the question. I don't see why not but I am not holding my breath.
Finally, an announcement on the Front Office page! But still no timetable. Sadly, all this is moot if MLB has to shut down (and it looks pretty dicey as of today.)
