Tim Visser admits Saturday's match against Wales will go a long way to determining if this is a successful Six Nations for Scotland.
Both sides have one win from two matches so far, the Scots following up an opening day win over Ireland with defeat to France in Paris.
"I've learned in the last couple of years that our Six Nations can make or break with only one game," said the Harlequins wing.
"It's important we get a result here."
Wales opened their campaign with a resounding win over Italy in Rome, but are also now in need of a win to keep their title challenge alive having lost to England in Cardiff last time out.
- John Barclay to lead much-changed Scotland v Wales
- Jonny Gray - Scotland's unassuming hero
- Five-week tournament would be impossible - Stuart Hogg
- Finn Russell column - I'll learn lesson from Paris blunder
- Irvine and Nicol back Barclay captaincy
Scotland have not beaten the Welsh since 2007 but Visser insists that fact is not weighing heavily on the squad.
"The stats don't lie. Wales are a good team," he said.
"We've had some narrow defeats against them in recent years. I remember losing here by three points a couple of years back.
"Going to the Millennium Stadium is hard but it's obviously a different game at Murrayfield. I remember sitting in a press conference before we played France last year and it was a similar story and we beat them.
"Statistically it (the third game) is always a key game. If we get a win then we are in a good position going forward and a position we want to be in."
Visser will start on the wing in place of the injured Sean Maitland and is looking forward to linking up with in-form full-back Stuart Hogg, who has scored three tries in two matches in the tournament so far.
"I remember when I first joined Scotland back in 2012," Visser recalled.
"He was just a young boy and seeing what he's grown into in the last couple of years has been brilliant. It's only going to benefit the players around him, especially the wingers when we link up with him.
"There's some stiff competition at full-back worldwide but especially in attack he's one of the best out there."
'For both sides this is huge'
Wales' record points-scorer Neil Jenkins echoed Visser's view that this is a match neither side can afford to lose if they wish to retain any hope of competing for the title.
"If you win one out your first two then the third game is always massive," said Jenkins, now the Wales kicking coach.
"It can get you back in the mix for the championship. For both sides this is huge and both need to win to give ourselves a chance of staying in the championship and winning it.
"Scotland have been very good. They had an outstanding win against Ireland and were very close in Paris a week later to coming away with a victory. Probably looking back they will be disappointed they didn't win that game. We know it's going to be a tough game, it always is up here."
