From an outsider's perspective (albeit one with a slight 'angle' - having worshipped the man as a player) I reckon he's performed a minor miracle, with your gates and finances, to keep you in the League.
We (Morecambe) are a similar club in many respects and we've done well to get where we are - our further progress will depend largely on our ability to develop a new stadium (with its associated revenue streams) and the continued very well-structured support of a group of reasonably well-off directors and a very well-off chairman.
If that does continue to help our finances grow then we'll be okay. But any significant problems with any of that and I'd say Sammy Mac would be performing miracles to keep us in the League.
Of course the extent to which your position is being hampered or enhanced by Coley will only be discovered when he does eventually go and that is a big risk.
I'd suggest it's a risk that should only be taken when you've really got nothing to lose.
