Why?
Most folk don't use cash in the shops and petrol stations any more. Buying anything online is cashless. You can even go cashless in the Novar.
The cashless society is not far away and it's here to stay.
That defence is a liability - 2 hopeless full backs, a makeshift centre half and another centre half who's looking well past his best.
Urgently needing some bodies through the door.
At present the left back position is a weakness. I'd hope that we are looking at Paterson and that Dick would eventually be back up when Lang returns to full fitness.
