That's reasonable.
I'd argue making a rational assessment of his ability to manage in the championship is difficult given the conditions he's operated under, the likelihood is that no-one here has a full picture of how bad they've been until perhaps he writes a book about it. Time may tell a different story, if he goes on to success elsewhere then some of the people pointing the finger at him may feel differently.
However the last point you make is a valid one. He's lost too much support and he's too associated with the misery of the last season in particular for any new owner to continue with him if they want the bounce from a fresh start. My guess is he's probably happy to go as well, the club has been a basket case for a long time now and isn't helping anyone's career prospects including his.
What still gets me and one reason why I'm on this thread wanting to talk about the finances and not this subject which doesn't belong here, is that there's several of you that are happy to abuse the man on a personal level because you've not enjoyed the football on offer. Here's a fucking newsflash, no-one has enjoyed the style of football on offer, but some don't use that as an excuse to call a guy trying his best in very difficult circumstances, a cunt. This when you have the very definition of the word owning the club and making the decisions that undermined PP and everyone else in the process?
The fact you're doing this as he's giving his time to go in and help the administrators and the club despite he and his staff not being paid since February is one more reason why he deserves at least a basic level of respect, whatever your opinions of him as a tactician. He's conducted himself well throughout despite being under immense pressure. I'm grateful for his efforts for the club during his time here and I wish him well in his next role.
