You are assuming that it was the stadium alone which caused the improvement in fortunes. A new chairman and significant increase in investment in the playing squad was what improved the quality of football which is what increased the attendances.
Without Ron Martin being replaced with somebody who is prepared to spend money on players, we will stay in the lower leagues and once the novelty of the new ground has worn off attendances will be lower than present as it will be far less accessible.
Do you honestly believe what you're saying or are you on a wind up?
