The suggestion that FA don't give a toss about steps 3 downwards has an element of truth in it, though. Certainly from step 5 down. If the three step 3/4 leagues have a united front on pretty much anything,- regardless of the effect it has below - they go along with it. Presumably because it's easier. The Conference, NPL, Isthmian and Southern each have far more individual influence than the whole of non-league football below them.That's just a lazy cliche. And, from your previous post, presumably this separate body should be aligned with the professional game?
While I can see why they did it, the decision to void the season so early does seem to have been done because the FA would rather concentrate their efforts on levels they give a damn about.
