The shake up of Scottish football is long overdue, that is a fact, but I see this as a desperate attempt to somehow keep their precious Glasgow cheats team in the top flight or, at the very least, make it easier and quicker for them to return (i.e a division / season less for them to return if they started where that should do..at the bottom). I also agree with the fact that it would be unfair on those clubs that eased off the gas towards the end of season not knowing that a higher finishing place would determine their division for next season. That would be unfair (hmmm, sounds familiar that!).
I also concur with CaleyD's view that, in the current climate, it would muddy the waters further.
