Leo Cullen has moved to silence critics who've pinned Leinster's below-par performances on Nienaber this season, calling him a 'defensive genius' and crediting him with significant value across three seasons at the province. Ahead of Friday's URC Grand Final against the Bulls, Cullen highlights an intriguing subplot: Nienaber's defensive system will go up against Pollard and Le Roux, two men who know it intimately from their Springbok days. Cullen also tips his hat to the Bulls' resilience — citing their comeback against Glasgow from 21-3 down in the semifinal — while acknowledging Leinster carry the weight of a painful Champions Cup final loss in Bilbao into this week. The piece is essentially a pre-final Cullen presser unpacked, but the Nienaber dynamic and the Bulls-know-the-system angle give it real substance for Bok-watchers.
