Rallying from 15-points down to grind out a gritty win over Wales demonstrates Scotland's growth as a team, according to back-row star Matt Fagerson.
The Scots' Six Nations challenge was hanging by a thread as they trailed 20-5 with half an hour to play at the Principality Stadium, but they scored three tries to snatch a 26-23 victory.
A criticism of Scotland in recent times has been their inability to come through difficult situations, something they did impressively in Cardiff.
"I think the second half especially, the belief was always there," number eight Fagerson told BBC Scotland.
"We spoke about how we were going to get up and put ourselves in positions to score.
"Once we got into that finish zone, we had a try disallowed off our trick play and that was a bit frustrating.
"The mental fortitude for the boys to then go back and put points on the board to put us into the lead, that's a massive growth in this team.
"There's plenty of years gone by that you've probably watched that we probably wouldn't have done that - that's a big positive."
