I sim one day at a time, doing the following:
- all promotions/demotions/DL assignments at all levels
- set daily lineups at the MLB level
- read all box scores for my teams at all levels each day
- track prospects and potential prospects on a daily basis
- check the waiver wire, trading block and transactions list daily
- make all draft picks
- handle all free agent signings
It takes me a while to get through a season, especially with grad school classes always chewing up some time. But I can usually play 3-6 games after morning while I eat breakfast, so it takes about 2-3 months for a full season.
