The squad is a bit of a rag tag bunch of players due to SPL and Championship clubs not wanting to release key players at such an important time of the season. There are only 18 players named in it, and just three strikers (I'd have had Queen of the South's Stephen Dobbie in it, but that's just me).
Nonetheless, it's a fine achievement for Scott to get called up and shows that his efforts are being recognised. The big defender has been capped at just about every youth level for his country and it is surely only a matter of time until he makes the full squad.
