I think this is very nuanced and covers my point really. I always liked Moyes, and honestly the following 10 years have really only re-enforced my view of how well he did.
But the 62 year old Moyes simple isn't the 40 year old Moyes. I'm not saying he is worse, but he is different. As a manager his strength was that he was a slow builder. I'm not sure he will be given the time to do that, and I think we need someone younger with a more fundamental vision.
Id also say, your first appointment as new owners is very important in setting the tone. Internally, but also to the wider football world. I'm not sure Moshiri ever really recovered from Koeman and Walsh, and certainly not when it was compounded with Allardyce. Any chance of putting in a proper structure was gone.
You don't get lots of opportunities to put the right structure in. And a 61 year old Moyes, who would alienate a section of the fans would be a missed opportunity.
