Well, for a start, it's such a wishy washy question that it doesn't really have a point other than acting as a strawman for perceived problems people are clutching at. What is any teams "identity" and does it last for any sustainable amount of time?
We have problems, this is not in question. Are some of them a symptom of the direction we have taken since Moshiri took over? Undoubtedly. Was that direction widely lampooned when it began? No, not at all. In fact, because of the years of austerity, it was welcomed.
Unfortunately, we hired the wrong manager in an attempt to do the wrong thing that everyone called for. Instant success. Had Moshiri decided to wait, patiently build, and refused to lean towards the fans hostility to the then current manager, he would've faced just as much criticism.
We have essentially gone down the some would say foolish route of gambling and doubling down 2 or 3 times in an attempt to claw back what we had lost. If any one of those gambles had paid off, he would've looked like a genius, but they haven't, so it looks bad and we instead have to regroup.
For every decision he could've made, there was at least 1 other option that may or may not have stood us in a better place than we are today. And with hindsight being 20/20, it's easy for any of us to point out which particular 1 we would've/could've/should've done differently.
Regardless of what you think of him, and the current onfield situation, which is as a result of a combination of poor fortune (missing a host of our best players in quick Succession) and overspending in an attempt to do things quickly rather than patiently, we are where we are. We may have appeared to be in a better situation before he arrived, but punching above our our weight, albeit fairly consistently, was not sustainable long term, just as the overspending we tried to cure it with was as well.
We need a good few years to turn this around. It was never going to happen overnight. People need patience and to apply a bit of reason rather than reacting to every event like its ushering in the end of days.
