For me, I felt like someone like Potter or Howe would drown managing a club of our size. I think all the managers we've had (at least since Martinez) have seemed overawed at the scale of the job and club - even Ancelotti. And by that, I know that he has managed clubs far bigger than us, but I get the impression he thought it'd be a smaller club than it is.
Marco Silva seemed completely out of his depth. However, I do rate Potter (whereas I don't rate Howe at all) and believe that he has the ability and nous to go right to the top - but everyone has to start somewhere. Guardiola is amazing but his first job was Barca, then Bayern, then City. If you start at the bottom and want to play good football and be a bit different, your task is considerably harder to achieve. But If you start at the bottom, it can really focus and improve you, and if we apply that logic to players like Godfrey, why not to managers?
What Potter did with Osterlund was amazing. I was hugely impressed by his Swansea team and generally like watching Brighton. But I feel like we are in such a mess that my no.1 choice has always been Galtier, followed by Rangnick, followed for Favre because they build and have plenty of experience.
However, the more I think about it, the more I warm to the idea of Potter (although not above the previous 3). I think that most of my fears with him stem from the fact the squad is awful, the club is badly run behind the scenes and that I don't have full confidence in Brands. I feel a manager who has never held a post of this size before may be overwhelmed if those things are not in place for him. However, at some point I feel like we are just going to have to place our trust in Brands and ensure we get a good coach in - which Potter is.
What I would say though is that, if we appoint Potter and it all goes wrong, equal share of the blame has to go to Brands. If they appoint a coach like Potter, the club need to bend over backwards to support him in every other way, otherwise it will be a disaster. But I came to the conclusion that that feeling of unease isn't really a reflection on Potter's ability.
