Going into the Rugby Championships for the Springboks to be successful they need a few things to be done right with a little bit of luck as well.
The All Blacks will go into the championship as favourites again with the Boks, Aussies and Argentinians to fight it out for second place in my mind.
We expect a much closer championship than what we have seen in recent years with the Aussies and the Boks that can push the All Blacks this year.
The Aussies and Springboks come close at home in the last few years and they need to covert them into wins now.
The Boks are already without Vermeulen which is a major blow for the Championship but in Whiteley we have a different number eight player.
That does not mean we are worst off, in-fact Whiteley brings something else to the team than Vermeulen and with a young captain in Kolisi Whiteley will play a vital role in the leadership of this team.
His interplay is brilliant which links players on attack and the option at lineouts is crucial.
The Springboks will have to win the forward battles if they want to have any chance to succeed this year.
That start with the tight five but even more important will be the battle on the ground and the small battles in the set pieces.
This brings a player like Marx as an very important factor in their success or failure.
Erasmus biggest headache will be his trio. Finding the right combination will be crucial not just in the way they play.
Erasmus has indicated earlier last week that Marco van Staden, Siya Kolisi and Francois Louw will start in the back row at some stage of the Rugby Championship.
Erasmus sees Louw as a contender for the number eight jumper as well although it is expected that Whiteley will wear the Springbok number eight jersey.
It will be a huge risk to play Louw at number eight. He is not a specialised number eight and the combination of Kolisi, Louw and Van Staaden may bring more problems than answers for Erasmus.
Du Preez has not done many things wrong when he was handed the number 7 jersey the last couple of years and then you have Brink who has been the star player this year in Super Rugby.
With Kolisi certain of his place as captain I would like to see Whiteley and Van Staaden starting against Argentina but we will most properly see Whiteley, Kolisi and Louw running onto the field this weekend.
The fact remains that Erasmus will have to make up his mind soon as we do not want to see a situation where we cannot settle on our starting trio against the Aussies and New Zealand so the two test against Argentina we are likely to see Erasmus find that combination.
