It started going wrong the day Ashworth left - that's when we abandoned the long term plan and strategy that had seen the club on an upward trajectory for several years.
Peace had already decided to sell the club, but with that gone he decided to just keep Premier League status so he could get the most money, so he appointed 'survival expert' Pulis. Then he sold the club to the first person to stump up the cash, having gone for a short term approach in order to try and preserve Premier League status.
From then on, everything has been downhill. Pulis might keep you up, but he works season-to-season, leaving the next guy no solid foundations to build upon. There might have been somebody out there who could do a better job than Pardew, but the recruitment process was flawed. The squad is imbalanced in terms of both type and quality - how are Krychowiak and Sturridge in the same team as Championship-level dross like Robson-Kanu et al?
Simply put, this is what we have got for several years of short-termism and treading water. And as I've said before, if you try to tread water for too long you will drown.
