What's the big deal with experience?
Darby, Ward and Ferry had only played a handful of games between them and they all performed pretty well. More relevant is that Cuthbert had only played 38 times before joining us, both LJF and Morrison have played more games than that now.
There's nothing wrong with a few players having a lack of experience. The problem is when you have a whole defensive unit without experience, or perhaps to put it more accurately, some kind of leadership, which usually only comes with experience.
