I think gutting and turning over an entire squad in one window is a massive mistake and spells doom. Getting rid of the **** kickers this window in Cannon, Moncur, Eaves, Wilks, etc. is fine, and replace them with quality first XI improvements, then get rid of your Elders, Coyles, Slater, Honeyman who are around about first XI but not really anymore the following summer makes far more sense. Ripping the bandaid all at once won't work IMO. But hey, what do I know?
Why does it spell doom though? It's fair to say it won't perform at the peak of it's powers but I don't see why it spells doom. The players coming in are a much higher calibre and even if we have a steady season, we should still be top half. Last season, we couldn't score and had to play a back 5 along with 2 holding midfielders to keep the door shut. I don't really see how it can get worse.
