Stuart Hogg held his hands up for the error that cost Scotland the opportunity of snatching a draw against France yesterday (Sunday).
The fullback missed a kick to touch, allowing the visitors to seal a 15-22 victory – their first at BT Murrayfield since 2014.
“I made a schoolboy error, it’s as simple that but look, I thought we played well for 78 minutes of that game,” he said.
“A couple of mistakes didn’t quite go our way and we’re old enough and ugly enough now to realise we’ve made a mistake.
“I don’t need to be told a million times about it.”
Defeat to Fabien Galthie’s side, who avenged their Grand Slam-ending loss in March, saw Scotland’s winning run end at five matches, but Hogg believes their upturn since the Rugby World Cup shows Gregor Townsend’s side are moving in the right direction.
“I was proud of the boys’ efforts,” he told the post-match press conference.
“We fronted up for large portions of that game, forced France into a kicking game and we stayed patient in our kick battle.
“It was all about the team who cracked first that would end up on the wrong end of the result. We switched off for 30 seconds and allowed them to score.
“We know where we’ve gone wrong and we’ll look to make amends.
“We’ve not turned into a bad team overnight. We know where we’re going wrong and we’re excited about our next challenge.”
