Polly,
Look at it this way. The club just held a review that says all was great. People have a lot invested in not shaking the tree right now because more would fall out than just the coach. So, like the team selections, you are going to be looking at an unchanged lineup for as long as possible.
It's unprofessional as hell but that's what happens in this situation. Roly can't change because that would be an admission he was wrong. Ditto Bondy and the board.
