From a report on the radio last night, the sequence of events listed above is missing an important step - to be registered with the SFA the proposed club needs to have a firm offer of being included in a competitive league. Therefore they need to have the SPL vote sooner rather than later, as this underpins everything else. If the result was a resounding NO! then they would have to apply to the SFL and this adds yet more delay, before they can even consider any other aspect. As I understand it they have missed the deadlines for applications for the coming season to the SFL so why are we even still discussing it? As CaleyD notes above, time is not necessarily on their side and it supports the comment from Green that they may not be in competitive football for the next season which will give them the time required to sort it out.
The main problem in all this is the negative impact on all the other clubs due to the uncertainty of it all. Supporters are holding off on buying season tickets, no one truly knows who the 12th team in the league will be and hence the league fixtures are in limbo until this is confirmed. They (Rangers NewCo) should do the decent thing and just declare the next season as fallow, thereby removing all this uncertainty and allowing the rest of us to get cracking on our preparations for the year ahead. Of course decency is not one of their strong points.
Upshot is, as excruciatingly protracted this all seems to be, certain deadlines will force the issue and we are rapidly approaching that s**t-or-get-off-the-pot moment. And that cannot come too soon.
