there are no special rules beyond 100m DH, 5/10/20 drop...otherwise its straight tsn rules.
the adaptations are that you draft your entire team simultaneously and get everyone you want from the player pool that's still available when your turn comes up.
once everyone has drafted, we load by division, 1,4,7,10 in east, 2,5,8,11 central, 3-6-9-12 west, and when west is finished and league fills...frenzy that night since everyone supposedly has exactly everyone they want. free agent moves during the preseason and season are unlimited as long as your 100m budget allows.
