You are conflating multiple things.
I would not say that she is either without blame (although using the word blame in itself is revealing), nor immune from criticism. Mistakes have been made. Bad decisions look likely to cost us our League 1 place. That is obviously hugely disappointing. But in context, we are still light years ahead of where we were 4 years ago.
No-one wants to be in League 2. The next DoF appointment is key. We have to try and get back up at the first try, which will be challenging.
But thinking that having a local, successful businessperson who is also a proper fan is NOT the ideal custodian, is genuinely a crazy perspective. So what if she makes bad decisions sometimes? She's not likely to be perfect. If she can explain them, or front up, or apologise, then that's more than most would do anyway. How many owners of clubs are actually 'good' owners?
Our natural ceiling is halfway up League 1. Anything higher is great, but it's overachievement. When she talked about it, she was laughed out of the room. Then she referenced little Port Vale, and got pelters. So she can't win really.
I'm not happy with where we are. But we should be happy with the ownership, despite the shemozzle of the season.
