Not really. Hoffman was appointed to the board in 2008, at almost the exact same time he took on a huge task at Northern Rock. The criticism that should be levelled at him is that he did not resign from the board immediately because he clearly had no time to dedicate to the football club and was otherwise engaged. That's a valid criticism, but he was hardly involved hands-on day to day, certainly not the Tim Fisher of the time as you allude to.
He ultimately sussed them out and walked away, probably later than he should have done, but to directly attribute all those failures to him I think is wide of the mark and is trying too hard to discredit a bid we currently have no details of, and which involves up to 6 other individuals we have no knowledge of.
It will all come out in the wash, but for now, I remain cautiously optimistic.
There is no point scrutinising a deal we know very little about. If any bid is accepted then clearly then we need to see the plan and scrutinise all we want, especially if they are expecting supporters to buy shares. The transparency people want I am sure will come in time, for now, let's just let them do what they need to do.
