With Rennie using the Bulls match as a final selection audition before Ellis Park, Planet Rugby breaks down where Saturday's game will be decided and what it means for the Test squad. The key battles are identified as the set-piece and gain-line — areas where the Bulls' front row, bolstered by new arrivals Liebenberg, Bosch, and Abrahams, can genuinely trouble the All Blacks. The Liebenberg vs Segner duel at openside gets particular attention, with Segner still in contention for the third loose forward slot against the Boks. The piece predicts an All Blacks win by 20, noting the familiar tour pattern of South African franchises competing hard for an hour before New Zealand's squad depth tells — but flags Loftus altitude and the late release of Grobbelaar and Louw as variables worth watching.
