I don't think it was stupid at all. If Moyes was going to succeed it would have had to be with his own staff because he lacks charisma and the ability to engage people and quickly build relationships.
There have been a lot of messages on here praising the other coaches and implying that it erodes Ole's achievements. If anything, that shows me that he can do this job long term.
He is the manager, he calls the shots, yet he has the humility and people skills to immediately form a cohesive unit within the coaching staff. He got to choose 1 of his 4 backroom staff, yet look how they interact on the bench. You can see it is a team effort and the ability to build that environment in such a short time is a testament to Ole's management skills. People talk about that as if it is easy. Delegating effectively is one of the hardest skills in management and it took years for even Fergie to do it effectively.
When you factor in a DoF coming on board, with any other manager you would worry about clashes of ego and dissention within the camp. I just can't see that happening with Ole.
Who knows how things will go for the rest of the season. There are many challenges left to come and it's unlikely he will win every game but it will take a huge collapse for me to want anyone else in the role full time.
