Marc McCulloch wasn't sacked after taking out half a dozen parked cars in Edinburgh whilst drink driving. There is no reason to assume Sandaza would be treated any differently.
Adams didn't make his debut til the following week scoring against East Stirling in a 3-0 win at Muirton.
IIRC the guy we signed to replace Evans was Davie Lloyd - remember him?
Craig wasn't doing as he was instructed so deserved to be taken off. McInnes is in charge and it is his responsibility if it goes right/wrong. Why leave players on the park who won't do what you tell them?
