There is no doubt that Adkins was told to get the numbers down, as the clearing of the decks in January shows.
It wasn't fun to watch the football, but I suspect the behind the scenes situation was even more of a trainwreck than on the pitch last season. As best I can tell from ITK posts on this board and discussions with various people, at least one, and possibly all, of the following happened:
1. Adkins massively overestimated the ability of the players we had and the players he brought in.
2. The board changed its mind about the level of investment it was prepared to provide, or there were divisions within the board that prevented investment being made.
3. For some reason, Adkins lost the dressing room, or lost the respect of a good percentage of the players, some of whom stopped giving their best effort.
4. Adkins' tactical nous completely deserted him.
5. Adkins tried hard to introduce what he felt would be improvements to the way the club was run behind the scenes, but failed to achieve this.
I'd love to hear his side of the story, but I suppose that's what confidentiality clauses are for.
