I think it's a good move, especially if that means we could possibly move for some loanees. Having a young back up keeper is better than throwing in a young defender or whatever.
Like I said before most teams this season will probably have similar types of squad in terms of size and overall ability. Although with Dundee resigning Douglas, Weston and McKeown they do look rather solid at the back. But then again we still have McGurn, Ellis and hopefully Bert (if he agrees a new deal)
