I think it has already been announced that a head coach will be joining Humphreys at Glos. As far as I am aware, the club are looking at a number of candidates, and will present them to Humphreys, who will get the final say on the Head Coach, as well as the rest of the coaching team.
Just before Nigel Davies left, he was talking about what he was doing about the long-term plan at Glos. The impression he made on me is that he was as much a manager as a head coach, and I am not totally sure whether he could commit fully to either. I think the signs under ND were that Glos wanted to move to the DoR/Head Coach model. Splitting the roles like this makes a lot of sense. In fact, I suspect that more clubs will move towards it. Managing and coaching a rugby club seems like far too much responsibility for one person, and it is exceptional that you can get one guy that is suited to both tasks.
But I am bloody excited for next season anyway.
