Scott Pianowski's Tip Drill is worth a look before heading off to your draft. Just some basics to prevent you from doing something stupid.

I disagree strongly with one of his points though:

Draft to help yourself, not to screw someone else: Some rotoheads can't help themselves, they're willing to torpedo their own roster progress just so they can frost their rival who's just about to pick. The temporary joy sounds like a good idea at the time, but you might feel differently when you see the damage caused and your own needs that didn't get met.

The temporary joy is always well worth it.
