Agreed. With all due respect to the Scots they are the perfect opposition to test your young guns. Pieter-Steph, Etzebeth, Kolisi and Ntubeni from the bench (you brought him along, may as well use him) should all feature against marginal tier 1 opposition. Hell, I'd even rest de Villiers and go pure youth in the backline.
I would have like to see:
Willie le Roux
JP Pietersen
Jaque Fourie
Jean de Villiers (Would have played Serfontein and Kept Jean on the bench for a what if scenario)
Bryan Habana
Patrick Lambie
Fourie du Preez (I would have put screuder (sp?) on the bench and given him 10 minutes)
Duane Vermeulen
Willem Alberts (I would have played Kolisi and had Alberts on the bench)
Francois Louw
Flip van der Merwe (PSdT would have been my choice and I would have kept Flip on the bench to give Eben a break)
Bakkies Botha
Frans Malherbe
Adriaan Strauss
Gurthro Steenkamp.
This team offers enough experience as well as youth, also it includes JP and Jaques who both need some serious high level game time.
