In the contect of football Independence, it just meens these things need to to be able to be done as an Independent in football. If cracks appear in any of those things, then the positive cycle of reinforcement starts to break down and it brings them all down. When the program becomes 'unsustainabile' it means that the combination of things makes each thing worse and worse (few wins, poorer recruits, bad exposure, inability to schedule) ultimately that can impact the money and then it becomes harder and harder to sustain the program financially.
