Rassie has rotated his starting match-day squad more than any other coach in the World Cup.
(this whole season in fact-e.g. playing a B-team against Australia).
Unlike say the Irish, who started their first-choice team in all of their World Cup games, and in the warmups as well (I believe).
The Bok's constant chopping and changing of players seemed like 2 B-teams, instead of a first-team with certain starters and settled combinations.
Rassie has spoken extensively that he does not believe forwards can play too many tests in a short period - and still play at their peak.
Now suddenly the Boks are going into a semi-final with players that are battled hardened, but not overplayed.
