Until these young lads are tried we will never find out if they are good enough. Do players just get to their early twenties and become good players overnight? NO. They have to be tried, supported and given experience. If it doesn't work out then so be it, but you have to give them a chance before just saying that they are all not good enough.
I don't want to refer to football but I remember a certain Mr Hansen saying that you win nothing with kids referring to Man Utd.
