I don't think anyone, apart from the eternal haters, wants to see the manager replaced as it is as you say a ridiculous merry go round. But the question asked is in or out and it was prompted by the Forest game and what appeared to be a very poor managerial performance. Yes the players made mistakes but, generally, the majority of the members replying, thought the manager had displayed a fault, weakness, inability or whatever you want to call it, that brought into question, his ability to get the club promoted back to the Prem and, importantly in many of their eyes, this season.
The relevance of any other manager at any other club doesn't matter. If the current manager is replaced, and I don't think he will be, then there might e some comparison. And in reality, if it should happen, unless the club brought in someone successful from the lower leagues such as Robinson or Cooper, they would only be looking at someone who has fallen of that ridiculous merry go round.
