The first two years I think people were satisfied just being there. Just surviving and then going down weren't considered failures, it was an achievement just to be there.
The second two years were different. The first year we were quite safe, we dropped places towards the end as the players couldn't be bothered with the league games in the run up to the FA Cup final. The second season it was thought that we had our best team ever and that we should have a good chance of being safe and getting our best position ever. Things started ok but then slipped away, and then we got overtaken, missed some chances and that was that.
This time around I expect people have left behind the feeling of just being happy to be there as was the case in the first two years. Of course a few will now come just to watch some famous players, but most of the support won't. And paying premier league prices would mean I assume that some at least would want to see an effort commensurate with that.
The drop in attendance for our last session in the pl had only one reason imho. My season ticket jumped from just under £400 to over £500. That was the year we were punished for the first name change failure.
Once people stop going, they're hard to get back. The quality of the league doesn't matter when you're actively attacking the fan base. I'm surrised the attendance stayed as high as it did.
