Justin Marshall's read on the series decider is straightforward: Erasmus's decision to name a near-unchanged side — just two tweaks, one injury-forced — leaves Rennie with little choice but to respond in kind. With the Boks 2-1 up and carrying momentum, Marshall argues there's no logical reason for Erasmus to disrupt combinations that are working, and that continuity itself becomes a tactical signal the All Blacks camp must decode. The broader context sharpens the picture: the All Blacks head into Baltimore without Savea, Jacobson, and Tupaea, which Marshall acknowledges gives South Africa a genuine opening to close out the series. His counterpoint, though, is that those absences should galvanise the All Blacks rather than deflate them — the challenge of holding a draw against a side with its foot on the throat is exactly the kind of edge a Test player should want. It's a considered take on selection psychology and series momentum ahead of a genuinely high-stakes neutral-venue finale.
