On one hand, I agree - I'd like to see more youngsters come through, and I don't particularly rate any of the players you mention.
On the other hand, I'd really like to get promoted. And as much I don't really rate those players, they seem to have proven themselves as capable deputies, and all at least have championship experience, should they be called upon.
Is Norrington-Davies good enough to replace Johnson? What about T. Smith and Washington, Semple and Cranie or Gilmour and Lundstram?
The truth is I don't know and neither does Wilder, and I don't think he wants to jeopardise our chances by trialing these players in the 1st team.
I'm surprised Semple has gone permanently, I would have thought 1 more loan might have been the obvious option - maybe there were no potential suitors offering better than Ross County, and he really wanted to play.
