Even without sponsors teams like Derby generate a lot of money, even if they spend more than they make. They have great potential and banks and other lenders like that. Remember that as long as players are paid and the FA, league, etc. get their fees and they abide by the rules, they (footballing authoroties) are not that concerned with a clubs internal affairs, money problems or not.
Telford in contrast to Derby, cost a lot and made little money in return due to far smaller gates, cash flow in one direction. Once the main sponsor (investor) the chairman was unable to keep the revenue flow open they were bound to become history very quickly. Virtually all clubs at non-league level have folded not long after big spending backers have pulled the plug. Simple economics dictate that they will. Those that do survive are few.
As for plans being drawn up to deal with it. Well the Conference clearly stated at the start of the 2004/05 season that any club in administation or similar situation would not be allowed in the National Conference & Conference North/South. Telford clearly fit that criteria. Sadly priority is always given to removing those that do not pay their way or become a liability, and not to replacing them without upsetting the rest of the apple cart.
You got to admit that this sort of thing seems to be happening a lot more often these days. I hope Telford lives on in some form.
