If he can handle the bigger games in the Championship so well, as he did this with this Yorkshire derby, I don't really see why he can't be given a couple or more of the lower profile Premier League games at this stage of the season and see how he does. If as we expect, he copes well with them, then why not promote him?
I know there are historical reasons for caution but sooner or later, if he is to advance, he will have to make the big step upwards so why not now? If the Attwell experience is the problem, I can understand the need to be careful but, to be honest, I would say that so far Jones is in a different league anyway in terms of natural ability so the risk is minimal.
