See, this is where the failure begins. They crashed out, they let Southend, a club in a dreadful mess, overtake them. They had a decent team core?? Why was that? bc Hurst was brought in, he failed to save them but immediately brought in better players, some from the bargain bin, thinking that even if they went down they would be prepared for the opening day of the next campaign.
Swann brought Hill in, who arsed about bringing in kids, no prepping at all for what was to come just prepping to finish the season on 26 pts, emit soundbites and shrug.
That last sentence is bang in line with your final sentence. New personnel, top to bottom. But the emulating needed to start 3 months ago, instead it looks like the York/Stockport/close your eyes and hope spiral was adopted, the club becoming an ever more unattractive sellable asset.
