If Rangers really do go under (seems hard to believe that will happen), the worse case scenario, and not exactly that unrealistic, is that it spells the begining of the end for the Scottish League system being independent of England's...or at the very least Celtic and a few others abandoning it once the FA bow to pressure and give them the green light. You can imagine the mess there too. The FA assess which level a new club should enter the League system at based on their current playing level, facilities, financial structure, etc. You'd have to presume Celtic would be quite high up, and then they'd have to take someon'e place. It'd probably end up in the courts.
