I appreciate the passionate discussion here. Lots to weigh but don't want to let this sit too long. The way I see it, there are three constraints to this problem:
- Can't allow some / the majority of owners to play under rules and others not.
- Can't unreasonably impact anyone's chances to do well in the tournament.
- Can't delay the tournament much.
Given those three constraints, what we'll do is implement the rule as intended (ballpark must be from a season you choose) but anyone who is impacted can make changes to their team (or pick new players) from now through Saturday. Then we will get schedules generated on Sunday and games will begin on Tuesday. This pushes us back 1-2 days but not much. I will also check in with the impacted owners to see if they plan to make changes. If they do not, we will be able to start sooner.
If anyone does make changes, they'll need to let me know so that I can re-check their roster.
