The Rugby Championship is a tournament that could ultimately come down to squad depth. The strength of the replacements bench could be all important in those stalemate situations.
Argentina have a smaller pool of players to pick from, and as a result, they may be found lacking in the replacement stakes. Their decision to rest their key players and give game time to their second string, illustrates the inexperience of those outside the starting XV.
South Africa have a nice blend of youth and experience at the moment. This means that their bench is particularly strong. When Schalk Burger, Schalk Brits and Ruan Pienaar hit the pitch with 20 minutes to go, you know that the Springbok strength runs deep.
New Zealand, of course, will fancy their chances. Their bench features front-row experience in Keven Mealamu and Wyatt Crockett. They also have some exciting young players to bring on in the backs.
TJ Perenara, Beauden Barrett and Malakai Fekitoa have all had impressive Super Rugby seasons and could run riot against tiring defences.
Australia have the least experienced replacements, particularly in the way of forwards. Scott Higginbotham is likely to give the back-row a boost from the bench. There are some attractive options for the Aussies in the backs, though, Kurtley Beale and Pat McCabe among them.
The battle of the benches will be a close call between South Africa and the All Blacks. Australia will have to hope their starting team get the job done.
