I think it might be because of a lack of concentration. The clear-out was incomplete, the culture largely unchanged. Its difficult to see anything thats not a problem right now. Thank you for your feedback. More worrying might be that when they do try, its no guarantee either  although results in Europe make all this harder to explain.
The coach tried, but ended up failing to explain.
