I think this exactly my view also.We needed a change and so did Moyes. So while it's all gone awry for is since, I don't regret it as such.
We did need a change, we just made a string of poor decisions about what that change should've been.
Martinez was the first, but I think Koeman and Walsh was our biggest mistake. That set the course for what followed.
Moshiri totally squandered the opportunity he gifted to Everton by not having a coherent long-term strategy.
You've just got to hope Thelwell represents the start of us doing things the right way, but honestly who knows?
