Looking at this it seems to me that 3 or 4 teams could really struggle. ICT, Dunfermline, Dundee, Morton.
United have a decent backer and the rest make small profits. The only saving grace for Scottish clubs if it drags on is most players contracts are up at the end of may.
Wider scope apart from Celtic (who have a massive surplus), Aberdeen and Hibs (with new backers), Hearts (Fans pledges) and County (who have McGregor bank rolling them) the rest may struggle if it goes on any longer than a couple of weeks.
