I think that Thelwell has been the least worst of our DoFs when it comes to player recruitment, hardly a ringing endorsement. I find it impossible to judge the remainder of his role.
I'm convinced that there are people out there that could do a far better job.
However if you bring in someone like Moyes with a proven track record of recruiting good quality players at modest fees then you are stupid not to allow him to be heavily involved and probably lead on player recruitment.
In fact it's interesting that Wham have just sacked their DoF and their statement specifically referred to allowing Potter to bring in his own head of recruitment.
I think that Thelwell's time is up. I'm sure that we will get a far more experienced and capable DoF. The direction that TFG go in terms of player recruitment will however be illuminating. If the new DoF has overall say in player recruitment then I'm not convinced that Moyes will be here for the long term.
