The last thing you want on draft day is a brouhaha over your league's rules. There are many scoring systems and nuances possible. You need to set your rules well in advance so that owners can base their draft picks on the scoring method you've chosen.
You should make sure owners are aware of the draft system. The serpentine (or snake) draft is the most popular. In this system, the order of the draft reverses with each round. The owner who drafts first in Round 1 drafts last in Round 2. Some leagues use this system, but reverse the order for the third round, so that the team picking first in the first round picks last in Rounds 2, 3 and 4, then first in Round 5. Some leagues use an auction draft in which players receive an imaginary budget and bid on each player proposed.
Owners should also be aware of:
- Trade policies
- All fees and prizes
- The Web site you will use and members' passwords
- Methods of settling any disputes that arise later
It's a good idea to make up a short rule book in advance and distribute copies to owners on draft day. One thing you should guard against is the temptation to change rules after the draft. Expect a lot of grief if you do.
