Public Leagues are guaranteed to have 10 teams for the draft. If a Public League is not full prior to the draft, teams are added from a pool of available managers to reach the required 10 teams.
Custom League drafts run as scheduled with as few as four teams signed up.
Custom Leagues with less than four teams at draft time do not draft. Instead, they're switched to become a pre-draft autopick league as soon as their draft time passes. These leagues then need to get a fourth team registered and reschedule their draft.
No live drafts are held after Saturday, September 30, and no leagues are drafted after Saturday, October 14. So, all autopick teams and leagues must be switched to Ready status by 11:59 p.m. PT on Friday, October 13. Likewise, all offline draft leagues must complete and enter their information, and click "Begin Season" by 11:59 p.m. PT on Friday, October 13.
Any offline draft leagues not set to Begin Season by the deadline cannot compete in this year's game.
