Ozie: Yes, there will be a way for you to pre-rank players if you can't make the draft. Go to "My Team", then in the box where it says how long until the draft, it'll give you a link to the Pre-Draft Player Rankings. Also, you don't need any offensive linemen for fantasy football. They're only necessary to protect the skill guys.
Everyone else: It won't hurt to leave the Black Market open for now, but I'll definitely delete it if it doesn't get 10 teams by about a day or two before the draft.
Also, thanks to everyone who joined! There are 7 in the standard draft league, and 5 in the auction. I'm hoping for 12 in the standard and 10 in the auction, but I'll run at 10 for either.
