Should the new manager finish any lower than 8th next season then there will be calls for him to go no doubt. There's no doubt Hess was afforded extra time by fans and the chairman due to his standing at the club. Would the new guy be afforded as much time?
The new manager should be given at least the same amount of time as Hess was, of course that is dependent on the fanbase. As you say I think Hess was given the benefit of the doubt too much, unlike Stimson who was hounded out for pretty much the first day. Does that make football fans fickle hypocrites?
... yes but that is the nature of football. I am not sure how the fans will react to the new man, but there is one thing for sure if he starts winning he we be lauded as the best thing since sliced bread.
