I would say whoever finishes 9th will win the playoff and remain the in the Championship.
It's such a crazy league that anything can happen, but I would say Arbroath will finish bottom.
Dunfermline have games in hand, but are they winnable with their current injury crisis? If not, I would say they will drop into that 9th spot.
QP,Ayr and ICT should have enough to escape the relegation play off spot. If the Pars do get on a wee run I would say QP will drop to 9th.
