I think it's pretty simple, to be honest.
As director of football, it's Rudkin's job to facilitate player movements in and out. Correct?
But thanks to him we have a number of unfathomable squad situations going on. Not least having two Championship level goalkeepers – Iversen and Ward – (one of them a full international) on our books since last summer, while they have been surplus to requirements. And that is just one example of a long line of odd decisions/outcomes (such as regularly failing to secure income from players who leave for free at the end of contracts). The latest oddity was the failure to move anyone out during this window – yet flying an Italy international to our training ground but failing to sign him for vague, "administrative" issues.
So either:
He is useless at his job and is to blame.
He isn't in control of his job and others are making the decisions for him (so he can't be blamed, but is redundant).
In both cases, it is hard to argue that he adds any value. In fact, I'd argue that he is a drain on resources.
