Not sure about that. Exeter has only one other league club within 80 miles.
Not sure how much an 80 mile radius from Northampton would extend but probably south Yorkshire to Cambridge to all of London and all of the West Midlands.
That's a naughty and largely meaningless geographical stat Pedjy
If you are going 40 miles east you are getting closer to Bristol and Bournemouth. It's a bit like saying that Aberystwyth is a potential sleeping footballing hotbed with little competition.
They are more into pasty's and clotted cream down there.
To support your point though, that is why I never buy our catchment argument. We have Leicester, Villa, Coventry, Watford, Oxford, P*sh, MK, Brum, Nottingham, Luton, North London...all an hour or less depending where you live in Northants. It would be generally interesting to know how many people regularly follow other teams who live in the county, because you can effectively cross them off. For example, my brother travels to Anfield.
You have to draw them in when they are kids and find a way to keep them coming back, which is difficult at our level.
