In other leagues I've heard you can set your own pre-draft rankings. I would assume that you would have to set it to autodraft with your own rankings.
Oh, sorry, what I meant was over-under on people forgetting to show up. At that point, Yahoo will start drafting automatically for them, using 1. Their custom rankings (it's on the Draft tab) or if none exist, then it uses the Yahoo default rankings.
So yeah, if you don't want to show up, it helps to set your own rankings. It's a bit tedious, though.
EDIT: The problem with autodrafting is that the system isn't trying to be very smart about it. It will pretty much draft to fill your positions and then draft for value. So it's entirely possible for it to ignore a really great running back in round 4 if it's already drafted your RB1-RB2-Flex spots.
You can show up or leave anytime during the draft, FWIW. The draft program will wait for your 90 second window to expire before it starts autodrafting all of your picks.
