No offence, Chris, but you do have a tendency to go off on one based purely on your own hypotheses, without any idea of how true they are. "Probably", "almost certainly", "my guess is", it's all just guesswork, but ultimately you've got no more idea than anyone else how much we've got to spend, and how close we are to having spent it.
As for the number of players in/out - our midfield was poor last season, everyone could see it. It needed overhauling. Evans has overhauled it. Whether the players he's brought in turn out to be better than the ones we already had remains to be seen, but Evans is doing something everyone agreed needed doing. Our defence was the 5th worst in the division last season based on goals conceded. A few changes there to try to strengthen doesn't seem unreasonable.
Holy and Eaves left of their own accord, nothing Evans could do about that, so they needed replacing too. But apart from them, are there really any others of the players that have left that people would have wanted to keep? The players worth keeping are still here - Ehmer, Fuller, Ogilvie, Charles Cook, Hanlan, List. Zakuani too, although it remains to be seen whether he'll be considered a regular starter. Byrne was OK last season, although I suspect there are better options available, but he'll be a handy player to have as backup.
I'm no fan of Evans, and what he's doing here might be the same as what he's done at other clubs with varying levels of success, but I do think it needed to be done here.
