I've no idea if that is true or not.
How many of the conference sides aren't professional these days?
Also how many of them have grounds which wouldn't be good enough for the football league? Can't be many.
Hmmmm weren't Crawley making 6 figure signings the season they romped it? Ditto Fleetwood last season?
Agree with you but then the same ground grading rules would have to apply.
