I assume some of the cheap lazy options that have been talked about are Archie, Doolan and potentially Graham. Even although I see them all as different situations, it is hard to argue against the eventual permanent appointment of Archie and Doolan. As an interim, Archie was part of a group that had been reasonably successful upto that point, the manager had left(not sacked) abruptly. It seemed pretty obvious to appoint him as interim. And then he started winning games away from home, which we had stopped doing under Macnamara.
Doolan was definitely out of the blue as interim as he had only been in the door with the academy for a few weeks and probably had had little to do with the 1st team. But again his results merited the permanent role.
I actually think it is a bit harder to justify Graham as interim as he has a coaching role with the 1st team and is team captain so has a fair amount of responsibility to where we find ourselves.
