You do remember correctly. I backed him to change things up in 2017, and bring the bew style he promised. But he didnt. And once this was evident i wanted his head. From memory this was about 1/3 of the way through last season.
My reasoning for this was that he deserved the chance to make the changes we needed. But once it was clear that nothing had changed, then it was clear that his time was up.
If my opinions are worth only as much as used toilet paper, then it is a certainty that yours is worth as much as what the toilet paper was necessary for.
