Definitely a disconnect between manager and competent professionals here. However, in such a situation, realpolitik means the manager will take the hit if he can't make the best of what he has.
Frankly, if these were Moyes signings he's not getting the best out of them. If they weren't Moyes signings and he is benching them, then he's he's not the right manager for our competent professionals.
Whatever we think of Angus and co - not much would be my take - Moyes is on a hiding to nothing throwing his toys - such as Dibling - out of the pram.
