I would go with with nobody from PL relegated, Leeds and WBA promoted, and the PL stayed at 22 permanently.
For a club like ours, the thought of FIVE relegations doesn't bear thinking about. NSC would be a permanent bin fest.
That is a very good point. You would like to think that the *lawyers/clubs would have drawn up something in the event of a season not completing. A war for example (we have had them before).
(*Unless someone like Donald Trump drew up the rules)
