I think if we had employed someone like Warnock at the start of the season we wouldn't be getting relegated. In fact, I think at the start of the season, instead of poaching Preston's manager, if we had went for the person they replaced him with, Alex Neil, we wouldn't be getting relegated.
I certainly don't think if more fans attended games we would stop up, but things are going to be like this for a long time (very little/no transfer budget) until the debt is paid off. If more fans attended (especially the ones who think not going will improve our situation) then the debt would be paid off sooner, and then things would start to improve.
