J.J. HarmseSydney - Gio Aplon's injury might not only open the door for Patrick Lambie to start his first game for the Springboks, but could also give coach Peter de Villiers the chance to determine Lambie's potential for the Rugby World Cup.Click to BUY the Springbok kitchen"Lambie is the logical replacement for Aplon. Who else could one use there than Lambie," de Villiers asked."He has the potential to become a big Springbok, it's in his genes to play top rugby. However, would he do it as a flyhalf, a centre or a fullback?"It's a big ask to do it against the All Blacks in New Zealand, but I have faith in him."The young KwaZulu-Natalian may well have started at flyhalf after Morné Steyn's poor performance against the Wallabies, but with Aplon out that is no longer an option.However, the Boks would do well to take a leaf out of the Wallabies' book, and use Lambie at flyhalf when they are on the attack. Steyn could then slot into the fullback position.The Australians often shift their flyhalf Quade Cooper to fullback when on the defensive. Digby Ione then defends the flyhalf channel and it works well for them.The Bok management view Lambie as a more potent attacker than Steyn - due to the youngster's ability to play closer to the gain line. It is thus a definite option to shift Steyn backwards during certain moves to give Lambie the opportunity to take charge of the attack.If it proves successful, it could easily become a trend the Boks could utilise during the World Cup.
