If you look at most of the recent seasons, there are usually one or two teams who have a small budget but get a well organised team and go up; Scunny, Colchester, Blackpool, Gillingham, Rotherham, Brighton and Carlisle look like they'll do it this year.
I think in Shez and the 3A's we've got a good infrastructure to be that team next year. Look how well we are doing with a full first team out at the moment? Imagine what we could achieve if we had most of those players available and playing regularly together.
I agree, we don't need to splash the cash, or change the manager, we just need a bit of luck on the injury front.
