I try to have a balanced view on the Prince.
When he came in we were in the doldrums in terms of our league position, but not the total carcrash overall that some might think they recall. Financially we were just about ticking over, the academy was doing well enough and we were still a more than attractive prospect to any half decent EFL manager.
But he did undoubtedly have a positive impact early doors, when he diluted McCabe's sell first and ask questions later policy. That in itself was a welcome step forward and although it took a while, with a few mis-steps along the way, he can legitimately claim his share of Clough's cup runs, the unmatched euphoria of the 2 promotions in Wilder era 1, and despite seemingly not making Hecky's job particularly easy, a 2nd promotion back to the PL.
However he also has to co- own the 2 relegations, one very embarrassing, the other utterly traumatising and to make it worse one that was absolutely set up in the preceding summer, with the horrible conclusion to the Ndiaye saga.
I think he cared, but probably also thought he would make a lot of money from us and couldn't quite appreciate why it became a struggle. As it turned out he saw that the realities of running a top end Championship/low end PL team are not easy unless you are either incredibly smart, or are able to access 10's of millions of pounds easily and regularly. He seemed to fall somewhere in between, for a while anyway.
Ultimately, we win together, we lose together and everything in between, right? And in the end it may have worked out alright for all concerned. I think that in the future and over time, the club historians will look at his tenure as the owner quite favourably.
