I made an account over there to check things out a little. Their Baseball 365 regularly costs $19.99, but new customers can get two teams for $14.95. I don't know if that includes the Baseball Daily thing - it's only available in-season.
If we wanted to do something like this instead of WIS Back to the Future, we'd have two options. First is Baseball Daily, which happens in-season. It appears you start with projected stats for each player and they get altered as the season goes on. The other would be like we do BTTF now - we draft before the season, wait it out, then sim after. The upside would probably be a more accurate sim. The downside is that they aren't as prompt as WIS - the 2016 season hasn't been released yet.
There's also a free demo which I may play around with when I have more time.
