That may have been true at some time, but I think it was no longer true when he came back the second time. Getting rid of Pearson showed that he cared more about getting back at his arch nemesis Crouch than he did about Saints. And I certainly don't buy the argument that he had no choice in the timing of administration. If he cared about Saints he would have clarified the situation with Barclays earlier (knowing we were on the brink), and then (knowing it was inevitable) ensured it happened a few days earlier. I have my theories why he let it happen after the deadline, but I don't want to be libelous.    
In an interview afterward Saints came out of administration, Fry said that RL and MW wanted to stay on during administration, and he (Fry) had difficulties convincing them otherwise. I wonder how long that took, and if these discussions started before the 10 point carry-over deadline?
