"There might be a case for The National League dictating that fines or points will be deducted from clubs unable to meet fixture obligations where COVID-19 is concerned."
What a ridiculous comment? It isn't the fault of the Clubs if they cannot meet fixture obligations due to players and staff contracting COVID.
Start issuing fines and points deductions and you will have clubs covering up the issue and playing on regardless.
The solution is simple, just extend the season by a few weeks.
