I didn't mean it as Moyes "restricting youth". He didn't hesitate to give Rooney, Rodwell, Vaughan, Vic... a chance. But I think Moyes is a manager that stresses a good defensive organisation (though that's nowhere to be seen this season). He refuses to play Coleman as a right back for example, prefering the much more solid Phil Neville. That's why I thaught Moyes might be reluctant to go with inexperienced defenders. It was just a thought as well. I don't know, it's possible Duffy just isn't at the level he was before his injury.
