Again, reflect on the facts. First season back and we excelled playing the football we'd become accustomed to. Wilder submitted a list of players he felt could strengthen us for the following season. To a man they went to clubs who paid better wages (Cash to Villa being one if I recall?), this is where frustration happened and where we failed to add better quality. Mystifyingly, we never learnt from this and failed to strengthen at the beginning of the following season. Don't know about you, but it makes me wonder about the Board and in particular the Prince.
The Prince took over in a heated dispute with McCabe, this club is now the Prince's, yet having got to the holy land, what happens? We rely on a squad that was aging, still with a few players who, with better additions, might have delivered results that might have meant we'd have remained a Prem club. We'll never know now, but these were decisions of the poorest level. Being a Prem club has so much pull for players who are ambitious. As for your poor appreciation of Wilder, again, we'll never know whether support from the Board would have given him the belief that this club had ambition. I don't mean winning the League, but maybe a cup run, or a season where we gradually improved on the previous season? In all of this I'm also not forgetting the contributions of Knill.
As for where things started to go wrong, maybe internal politics were at the root, maybe strong individuals didn't see eye to eye, and the consequence was the club became a casualty. Rather than grandstand about who did or didn't fuck up I'd prefer to ask those now in power what their intentions are for this club, which assumes they have the ability to answer truthfully and candidly. Treating supporters like adults would be a good start, rather than assuming that they'll follow this club with blind faith.
