Its simply a cost cutting measure.
As said, although it doesn't seem a good idea for the team/club, from a financial point of view it will still run without them.
The team losing doesn't make a difference to teh Administrator, he simply wants to keep costs low, and find a buyer, or retain enough oney to pay creditors.
Wakefield lost players that in hindsight did not really help financially at all once we were bought but the administrator did anyway. Just doing his job I suppose and I guess you don't become an administrator to be popular.
