We can change just the one rule and incorporate the Ohtani rule only. So, the manager can take Ohtani* out as a pitcher and the Ohtani hitter stays at dh.
Re-start your League! Select Ohtani pitcher card in the league from team roster in your league. Select the player option in the top menu, a drop down will reveal update player option. A window will open up showing Ohtani’s name, if his name is not there, the league didn’t restart. Add an asterisk to the end of Ohtani*. That’s it.
Only the person making the league file needs to make the change.
I don’t see any reason not to use this in every league. It’s just the right thing to do. The ghost runner, 3 batter vs reliever rule and other rules can be voted on for specific leagues. I agree that those sorts of changes should happen before the draft starts but the Ohtani rule is just the right thing to do.
