Yes, because it was adding an unnecessary layer of bureaucracy to the onfield side of the club.
They got shut of that to replace it with even more bureaucracy.
You cant run a football club by committee.
I've said for a while Dave that eventually the DOF role will eat itself. It was brought in to provide stability but in this age where every man, cat and dog is open to scrutiny, having a DOF no longer guarantees any stability.
However, it's interesting to note that we haven't actually appointed a DoF. The 4 roles are independent of each other and none of them holds a more powerful position than the manager, which you just can't say when you appoint a DoF.
Nick Cox - Technical director. His remit is to ensure that facilities, both medical and sporting are fit for purpose. He will also be performing this role for the womens team. He will have no involvement in transfer activity.
James Smith - Worked with Moyes for 10 years. Head of Scouting and recruitment. His job is to identify players, both personally and by using the scouting network he will help to shape. I highly doubt he will be going over the managers head.
Chris Howarth - He is there to ensure the scouting team can make the best use of analytics. He won't be dictating transfer policy.
Nick Hammond - Player trading. As in actually negotiating the in's and out's, he won't be deciding who is sold or bought, just working to ensure the club strike the best deals possible.
If one person - a DoF- was performing the above duties then he wields a lot of power, compartmentalised like this though, the power is diluted and not one of them can just ride roughshod over what the manager might think. It also means that all of them are also able to handle the same matters for the women's team.
