Wallabies coach Michael Cheika wants to improve his team's mental resilience. A good place to start would be to take the captaincy off Stephen Moore and give it to someone capable of playing for 80 minutes.
These days it's a surprise if Moore lasts an hour. His best effort in the June series against England was 62 minutes in the third test in Melbourne, and that, frankly, is not good enough for a test captain.
It undermines Cheika's aim of lifting his side's ability to cope when the pressure comes on late in tests.
Instead of 33-year-old Moore leading from the front in the final quarter, on comes replacement hooker Tatafu Polota-Nau, a once explosive player but one who is also slowing down. Worryingly for the Wallabies, Polota-Nau has also been recently prone to getting the yips at lineout time.
Big tests are won and lost in the final quarter. That's when strong leadership is critical, but unless Moore's fitness has improved significantly over the past couple of months, it would surprise if he lasted beyond the 65-minute mark at ANZ Stadium tonight in the replay of the World Cup final, a key match in terms of the Bledisloe Cup and Rugby Championship.
