In cricket, if a match can't be finish due to factors outside of anyone's control, they use a formula to decide who wins, effectively based on how well the sides have done up til that point in the match. The teams are all happy with this cos it's what they signed up before the game started.
If you'd asked the teams at the beginning of the season: in the unlikely event that a killer virus means the season has to be suspended three quarters of the way through, and after every effort is made to complete the season, if it's really not possible to finish the season before August, what should be done? I bet ten times out of ten they would all have agreed to settling on the positions of the league at the time of the suspension. Can you imagine them agreeing to just forget the three quarters of the season that have been played and start it all afresh? (hypothetically speaking, obviously).
The stupid thing now is that certain teams have so much to gain or lose from different scenarios that they can't be involved in any kind of objective decision making. See eg Karen Brady.
