Not sure why there is so much bashing of preston, I assume this is because they not a leeds, leicester, southampton or a norwich they dont have the right to be where they are so they will drop off, the same as what people were saying about us 9 years ago.
Confidence is a huge factor in football, we lacked it last season and got relegated with the most expensive relegated team in history, likewise there has been many teams promoted on a shoestring. Momentum breeds confidence.
We also have rode luck to get the points tally we currently have, the arguments to preston equally apply to us. They can drop off, but we can drop off as well, we will both drop off at least to a degree. As we not maintaining a 6 wins out of 7 form for the entire season.
