I think the biggest tell-tale sign is the ability to care. Relegation to league one mattered, I was sad, in the years building up to it I still had faith, hope and I wanted to go.
Now I just don't care, have little to no interest in the results or going to the games.
And the only way that changes is if the board change. We can change the manager and change the players but whilst the rot remains at the top then it's hard to care what happens because this is not the Leicester City that I fell in love with
