I'd like to think they'd come up with as fair a solution as possible, be it voiding the season or finding some way of playing out the fixtures fairly. Of course it's all hypothetical, but if they were to declare a champion in such a scenario that would be farcical and just couldn't see it happening. (I understand in both that situation and this, 1st place is technically up for grabs but no Rangers fan in their right mind* realistically believed there was any chance of that before lockdown began)
*I'm not inviting the usual snarky comments about the intelligence of OF fans with this turn of phrase by the way, so please refrain (not aimed at anyone in particular, by the way)
