Load league pulls all twelve managers and their profile pictures straight from Sleeper, so the field fills itself. You can still rename anyone, pick a marble color, or click a marble to wrap your own picture around it. Everything is saved in this browser, so you can set the field up now and run the race on draft night.
The seed decides everything — the track, the starting lanes, every bounce. Hit Shuffle with the league watching so nobody can go hunting for a seed that suits them. Slot order here buys you nothing: starting lanes are drawn fresh from the seed.
