I think Moyes is a very good manager, whose reputation has been unfairly tarnished due to him being stupid enough to take the Man Utd job. The performance of those who have followed showed he was not the real issue there.
Thing is, he is now labeled a dinosaur manager. Moshiri would never go for him as he wants to be trendy, at the bleeding edge, etc. The dinosaur thing is weird to me, as Moyes was never that type of manager to me, he always seemed like someone who would leave no stone unturned to maximize performance.
The other issue is tier one managers will not come here. We will always be getting flawed candidates as we have neither the financial muscle of a Man City, or the prestige of a Man Utd.
In some ways Moyes would be ideal, but I really cannot see the board going for it. Instead we will get someone like Cocu, even though he seems no better than Silva.
