I'm actually very into draft leagues, and I have no problem with a max cap in an exclusive ownership draft because, let's face it, you're not getting there anyway. But I absolutely don't see what the point is of running a full draft and then having AAA. If you draft well you're basically never using the AAA anyway. There are more than enough good players in the database to have 25 useful guys on each roster at the end of the draft. Somebody is going to get a couple of ridiculous stud bullpen arms out of that and get an advantage they didn't earn in the draft. Why inject that randomness?
Also, given that you've drafted, why inject cash? The rosters should be fixed already. And again - nobody is going to have a max cap roster. You're not going to need more money.
