Gregor Townsend has urged the British and Irish Lions side facing the Stormers to capitalise on playing the day before selection for the first Test against South Africa is decided.
Townsend admits that because performances at Cape Town Stadium on Saturday will be freshest in the coaches' minds when they gather the following day to pick their 23 to collide with the Springboks, the players have a unique opportunity they must seize.
It means the likes of scrum-half Ali Price, centre Elliot Daly and flanker Hamish Watson – players pushing hard to be involved – have crucial final auditions in the last game before the main event of the tour begins.
"Our players have learnt what it's like to come up against the Springboks," the Scotland boss said.
"Not many people have that opportunity and when you do it's a one-off game. It's a World Cup semi-final for the Welsh guys or a final for the English guys.
"Now they've had that experience of what they're about, the way they're going to play. The Springboks aren't going to change, we know that. They will be better for the hit-out.
"We felt that seeing where they are strong, maybe where there are opportunities, that's hugely valuable for the group that played, but also for those of us who were in the stadium watching."
