Steve Hansen has been watching the Rennie era closely and likes what he sees — a group that looks more settled and clearer in their identity than they did under Robertson. His read on Rieko Ioane is a useful lens: a player who lost his place, had a productive sabbatical at Leinster, and has returned visibly reinvigorated. Hansen credits both the personal reset and the coaching change for that shift. His broader point is that Rennie has found a style the players believe in, which matters enormously for on-field execution. The caveat Hansen adds is worth noting ahead of the Ellis Park Test: the fun-versus-stimulation balance is a knife edge, and the Springboks are precisely the kind of opposition that exposes any looseness in a team that's been winning comfortably.
