I think the key problem is the ownership and I’d focus on that rather than the likes of Graeme Sharp - I don’t think he’s a key part of the problem
Some fans don’t seem to have any resilience or perspective - football is so much about confidence and the fans help create fear at times in the players and staff, when actually support would help their confidence more. Some fans don’t seem to have the resilience to remain positive through difficult runs
It is not the fans who should show resilience, but the coaches and players. This separates the best from those who are not good enough. Resilience is not only about tolerating stress, etc., but also about learning. From this perspective, it can be argued that the fans have been too loyal for a long time, and the only way to move forward is to replace the decision makers. This is learning. Because the decision-makers make repeated mistakes, along with the manager, which go beyond the well-being of the fans.
It can also be argued that in crises you need clear information and a clear plan. This is completely absent. And aren't the fans what keep this merry-go-round alive, and weren't they the ones who really helped Everton through a tough time last year?
