I dont think Moyes will start him, the best he cqan hope for at present is some sub appearences. Even if he has the ability at present, there is so much more to consider, you have to handle young players with kid gloves, by their nature they are inconsistent, they may have one or two blinding games but they then fade a bit, as they are not mature enough either physicaly or mentaly to acueive the appropriate level of consisteny over the season. Thats why you dip them in and out of a team.
You also have to manage the expectation level around them, this thread is evidance of increasing expectations. For example if we dont sign another DM and start with Rodwell and he playes four blinding games then six bad ones, the level of frustration and criticism by fans could seriously hinder their confidence and development. Look at Neville and the critisim he gets in midfield, that would be hard and some what unfair on a younger player, learning and expeirencing the senior game for the first time.
So for me his appearences will be staggered we will see him at intervals and staggered appearences, untill he develops consistency and expierence, he may do it now for one or two games, but the trick is doing it in 45 odd games over a season, he no way ready for that, nor shold we expect it. Frankly Moyes just wont do it.
Its also important to remember Rooney was never a regular starter for us.
