Mate, no offence but this doesn't really make any sense
if we've changed every layer of the club hierarchy, where do you think the "inept culture" resides? Who exactly are you complaining about if it isn't the owner / manager / "personel at the top"? Maybe the issue is with the tea lady?
Or maybe it's harder than we think for a club that's been struggling with relegation for years and cycling through managers to sign players that are going to make a difference in moving them up the table?
Leadership and a change culture, yes circumstances haven't helped but the first way to change it is decisive leadership. Sadly it doesn't look like things are changing. Look at what happened at Newcastle(I know they had Saudi money) but they totally changed the culture and became decisive and changed the narrative. Everton hide, excuse , say it will do, make do, it comes from a Kenwright era of meekly accepting our place. When it won't that was horrific last night and the result of poor planning, poor recruitment a poor preseason. We will improve but to truly challenge we have to have decisive leadership that wants to push us on and think outside the box, for heavens sake Bournemouth, Brighton and Palace all are better at pushing on and progressing than us. With less resources or fans. The club just sits there and meekly accepts its place and hides from the fans because gambling actually puts their necks on the line. Again I am judging them now not in September, and now isn't good enough and I don't even mean we haven't signed amazing players I mean we don't even have a functional squad or a right back or a right winger.
The club needs to grow up and drive change and results if it wants to embrace the opportunity of a new stadium we are sadly flunking it currently. The culture of accepting mediocrity and failure and excusing ineptitude is carrying on so far.
