Every club should have a DOF/Sporting Director.
Without one you're putting all your eggs in a manager shaped basket, or even worse.... an interfering board.
Whatever you may think of Thelwell (it's too early to judge) having him there is far better than leaving it to the Brains Trust of BK/DBB/Moshiri/Agents.
Shows the absolute state of the place when DBB was positively glowing with praise when Thelwell presented her with an extensive list of things that needed doing, completely missing the point that these ommisions happened on her watch.
Appoint a DoF, let them get on with it. You can't measure their impact for 3/5 years so you have to stick with it.
