Wouldn't be the worst deal in the world but Smith is too good for this league. If he doesn't get his chance at the Dons i can see him doing well at somewhere like Killie or Thistle.
Id say he's worth taking a chance on. Really quick and direct, could be a long term replacement for Hayes if he can develop at the Dons. Shankland won't make the grade. Struggled with us this season in a poor team right enough, but hasn't excelled at Morton when they have been flying high. Maybe a lower end Championship player in there somewhere but not good enough for the Prem never mind Scotland's 2nd best team.
Looked like the kind of player we were crying out for until we signed Stephen McGinn a few weeks after. Struggled to get in the team since, only seen him once or twice, he could win the ball but then be really sloppy with possession and slowed our play right down which isn't the way Jack Ross wants the team to play.
Out of the 3 I'd say Smith has the best chance of making the grade. Would probably write the other 2 off, definitely in Shankland's case.
