Cotter took charge of Scotland for the first time on Saturday
Scotland got off to winning ways under Vern Cotter on Saturday and the new man in charge was impressed with a trio of debutants.
Glasgow Warriors duo Finn Russell and Gordon Reid pulled on a Scotland shirt for the first time, as Cotter's side beat USA 24-6 in Houston, alongside London Irish flanker Blair Cowan.
Full-back Stuart Hogg and fit-again winger Tim Visser dotted down for the hosts, who were also awarded a penalty try, but 21-year-old fly-half Russell stood out to the head coach, who took over from Scott Johnson after a disappointing RBS 6 Nations campaign.
"Finn Russell, you'd think he's played 20 or 30 games already," said Cotter. "He was composed, he kicked well out of his hand, he directed play well and defended.
"Gordon Reid at the first ruck took the ball and ran through the middle of it. Obviously he wants to be part of the game and that's really important.
"Blair Cowan had an outstanding game at openside, he kept pressure on the whole time. Their play-makers never really had an easy time."
However, he also conceded Scotland have a number of areas to improve on with a visit to Canada to look forward to next weekend.
"Obviously I'm happy because we got the win. I thought the players, despite the difficult conditions, played well," he added.
"With certain things, as all coaches will say, we have to do better next week and we're working on those.
"I'm really pleased with the opportunities created and I'm happy that we managed to get over the line. I thought we could've got over and scored another couple. We're looking at that but the opportunities were created and that means that we had initiative."
After Ireland's heroic big-game hunt of the Springboks and Scotland's six-try runaround of the Pumas, the challenge of engineering the most spectacular win of the autumn series now falls on Wales, writes Peter Jackson.
