As a Lincoln City fan who experienced a similar situation in 2000, although perhaps not quite as severe. I think clubs really to need to cut their cloth according to their situation, players are really the only assets that a club own and if they are good enough to be sold on then they probably need to be. There are 23 clubs in League 2 who have to be selling teams to make ends meet, but as someone mentioned above the idea is to replace them with players who are cheaper but just as good or better.
