Steven Kitshoff reckons the All Blacks will arrive in South Africa carrying significant fatigue from a gruelling northern hemisphere schedule, and that the Springboks should look to exploit that physical toll across the Rugby's Greatest Rivalry series. That said, Kitshoff isn't writing New Zealand off — he still sees enough in them to cause the Boks serious problems if South Africa switch off. It's a measured read from someone who knows what it takes to grind teams down at Test level, and worth a look if you want a former front-ranker's take on where this series could be decided.
