Craig, who was thought to be interesting Glasgow, tells Jeff Connor that he believes progress was made in South Africa but that Scotland must learn to be mentally tough enough to put games away when in a strong position.
"It's self-confidence, belief in ourselves. I was happy with my performance in the first test, but in the second, apart from the try, I didn't do a great deal.
"But the last 20 minutes it was all South Africa, and a good exercise in getting the defence right and getting used to playing with Hendo (Andy Henderson). On that tour he hasn't done himself any harm at all. He can find space and he is also good in defence, so that's another in the mix, along with Simon Danielli and Ben Hinshelwood, who are coming back from injury."
