The Sexton conundrum

THE level of attrition in modern day rugby means the need for squad depth is more pronounced than ever, especially in key positions such as out half. After all, even back in 2011, hosts New Zealand needed fourth-choice number 10 Stephen Donald to step up to the mark and kick the winning goal in a nerve-wracking 8-7 win in the final over France at Eden Park after Dan Carter, Aaron Cruden and Colin Slade had all succumbed to injury.
