Sure and Stockport have money and were better than Wrexham.I think Bolton will be strong again. And you have the wild card of Wrexham as well who will have money to splash around.
Peterborough will very likely be weaker ( they could lose a number of their better players).
Charlton and Reading are interesting. I am not as convinced as some by Charlton ( Jones did OK but hardly suggested that they will tear the league up next season- they will presumably spend quite big), and Reading still seem in financial trouble?
