Is there a full schedule somewhere of all the sims in a season?
That's a good question - something that would make sense to add. I'll put this on a feature list.
The immediate future will conclude the late free agency on Friday, training camp on Saturday, Monday will be the midweek before the first pre-season game, and then the first game will be Tuesday. Games alternate between weeks and midweeks, 6 sims per week with Sundays off, so the games will run on the same 3 days of the week all season long.
There is one final sim after the bowl game for the end of the season, where you can do any final contract renegotiations, followed by 6 early free agency sims, and then the draft takes 6 days. After the draft, it's back to late free agency, and the cycle continues.
