Factoring in capacity, corporate facilities, general state of ground etc...but most importantly, being able to make money out of it...I reckon, worse than Sixfields:
League2:
Forest Green
Stevenage
Newport
Crawley
Cheltenham
Morecambe
Macclesfield
League1:
Accrington
Fleetwood
AFC Wimbledon
*Luton is an utter dump but capacity is over 10,000 and they also have numerous boxes.
*Fleetwood is debatable given its excellent facilities, its just got a very small capacity.
*Wimbledon are having a new ground built, as ar Forest Green. Luton are also making good progress in that regard.
So out of the 92, I reckon theres 10 grounds that are worse than ours.
Interestingly, none of those grounds are big towns/cities. Even with my claret tinted glasses off, we should be a considerably bigger club than any of those on my list, due to catchment area.
When we moved into Sixfields we had a very decent 4th division ground, but so many clubs have moved on since then and our ground is now incredibly worse than what it was when we moved in!
I find it incredible how anybody can even debate otherwise, its plain silly. It needs sorting and the current owners are not doing it. Despite promising to do so on their arrival.
Thank you for identifying at least 10 possible worse grounds(you forgot Mansfield and possibly Burton)) than Sixfields. Your point about Sixfields failing to be developed over the years is reasonable. I would say that when CW moved on then any hope of ground development went with him. The team faltered and the succession of managers proved unsettling. Perhaps and I hope Curle is the new CW to inspire us to greater things. What ever people say it is a catlayst we need first; with team improvent and increased support. People do like putting the cart before the horse on here.
