They feed each other, but the club cannot say they haven’t had brilliant support and atmosphere from the fans during successive relegation battles. This fan base would be ready to explode if the team did even anything remotely good on the pitch but there’s hardly anything ever. How good did it feel around the club after we’d bested United away, everyone was absolutely buzzing, then it’s followed up by getting annihilated by rancid Spurs and Newcastle teams at home.
Of all the big clubs in English football, our fans have been condemned to suffer consistent, grinding mediocrity untouched by uplift. Our lows haven't been as low as those of City, Villa, Leeds, or Newcastle, but our highs have, basically, been mere pick-me-ups compared to theirs. The four clubs I have mentioned have all been relegated over the last 30 years or so, but City have won the Champions League and multiple titles (basically surpassed our entire history in three decades), and the other three have been in the Champions League, some in the latter stages. Newcastle won the League Cup to go with their European involvement. In that time, we, basically, had one joyous season of Roberto. And even that ended in failure to make the CL.
Moyes's best had the same outcome.
It's no wonder so many of our fans suffer from a poverty of imagination and ambition. We've not only been left behind by our former peers (the three big red clubs), but we've been surpassed by Chelsea, City, Spurs, Villa, and Newcastle. And that's before we contend with the small clubs having their greatest eras (Brighton, Brentford, Bournemouth).
Nothing will change at Everton until somebody at the top decides they want to change it.
