Genuine question, if that's your benchmark, would you be calling for LRs head now if he had stayed and managed the same points total Tim has so far?
Its a decent thought.
My answer would be that if Rosenior had the same points total and levels of performance we've had so far this season - I'd be questioning whether I think he was the right manager for the club - but I'm not sure I'd be calling for his head yet. Reason being he had a bit more good will in the bank from the last two seasons and we've seen him put together a decent side (even if some thought he was underperforming).
Walter doesn't have that good grace and I have nothing to base my confidence that he can pull it around. I still think there's a possibility that Walter can prove me wrong - but yesterday's second half showed so little progression in the side that I don't see where Walter's good tactics are going to suddenly come from.
