Scotland centre Mark Bennett admits it is frustrating that the national team keep falling short despite displaying some glowing passages of play.
at Twickenham on Saturday was Scotland's fourth defeat in a row in the Six Nations.
"There are little things that are stopping us from clicking - individuals making wrong decisions and errors," said Bennett, who scored a try.
"It's disappointing and frustrating, but we need to work out why that is."
The Glasgow Warriors player sliced through the England defence midway through the first half to cross the line, with Greig Laidlaw converting to pull Scotland level.
That ended a mesmerising start by the hosts, who are in a three-way tussle for the Six Nations title with Wales and Ireland, Scotland's next opponents.
But although Vern Cotter's team led 13-10 at the break, they were pinned back for most of the second period and the defeat followed narrow losses to France, Wales and Italy.
The 22-year-old Ayrshireman told BBC Scotland: "We are playing some good rugby and attacking really well.
"I think we can be a great side. It's going to come. We are putting top teams under pressure - in the Wales game and England game we really performed well.
"Our defence is one of our strong points as a squad and it's something we are really proud of and once it clicks it is going to be a great squad.
"We were just one or two passes away from absolutely tearing them up.
"We really weathered a storm from the England squad. They really started well and put us under a lot of pressure.

"I think the heart and character we showed to keep them out set us up for that next 20 minutes and there are a lot of positives to come from that."
The theme was echoed by Scotland's tough-tackling flanker Rob Harley, a team-mate of Bennett's at Warriors.
"I think we are close. It's just putting it together for 80 minutes," he told BBC Scotland.
"The framework is there for the way we are trying to play, and it shows when we are stifling attacks, getting good line speed in defence and when we are playing with quick ball and making gain-line, making breaks.
"It is a frustration for us.
"It's a process for us to learn what we are doing wrong and lift our levels. We are looking at how we can bring our standards up so every time we are attacking at our best and playing our best rugby."
In a whirlwind opening from Stuart Lancaster's England, the hosts scored one try and might have added another two or three had it not been for brave defending by Scotland and their own errors.
"It was probably the fastest game I have played in," was Harley's assessment of the first 20 minutes.
"Right from the start it was frenetic. Both teams caused the other problems with the pace of ball.
"There was chaos in both teams, finding gaps, making yards.

"When you had the ball to attack, there was a lot of space, the ball was very quick. But the same applied to defence; England got quick ball and played very well with their attacking shape and caused us a lot of problems."
Scotland round off their Six Nations campaign on Saturday afternoon at Murrayfield, with the visitors Ireland second in the table and looking to better England's result at home to France and Wales's score in Italy to lift the trophy.
