I’d say Blaney is a bit like Bevis in that he is largely fine but also capable of the odd brain fart.
I seem to remember him bringing the ball out from the back and inexplicably gifting it to an opposition forward , maybe against St Johnstone?
I think the best our defence has looked was when it was being marshalled by Butcher after January last year. If Butcher is indeed finished at this level then I think we need someone else of that style i.e. a calm composed organiser. We do look frantic at times , often under little pressure .
