Scotland head coach Vern Cotter believes missing a drop-goal at the end of the first period was a key moment against England on Saturday.
The Scots lost 15-9 in the Calcutta Cup but could have gone in at the break 9-7 up had Finn Russell been successful with his snap effort.
And the boss thinks had that gone over, they would have been in control.
"If we'd got the drop over and gone ahead at half time we'd have been in a great position," he said.
"We created opportunities but couldn't finish them off, and we weren't accurate enough.
"But there's a lot more to come from this team.
"I'm disappointed with the way they let those opportunities pass through lost ball, but those problems will be quickly identified and we need to put the frustration behind us and just prepare for the next game."
Cotter added: "We can do better than that. I know we can.
"We cut down a few basic errors and become more accurate and start believing again. I think that game was there to be won and that's the hard bit.
"So when we get ourselves in similar situations in the future we just need to be able to nail it, and those will be the basics of moving forward."
