One of any national coach biggest concerns going into a World Cup is injuries.
With the amount of matches players are playing in these days are taking it toll on either player fatigue or long term injuries.
There is a fine line that players and coaches need to walk. On the one side you want players to be properly conditioned going into the World Cup but on the other you also want them to be fresh and without any niggle as well.
2019 Will see the Super Rugby competition running straight through without a break before a single round of Rugby Championship matches.
Erasmus will have to work hard with his four Super Rugby franchises to make sure that his core players are managed during Super Rugby.
There is no way around it and the facts remains that with the amount of rugby being played by your top players, the effect of that is seen in the injuries every year.
It is clear to see on this current Springbok tour to Europe that certain players had just a few too many this year.
The Springbok captain Siya Kolisi has played over 1000 minutes in Super Rugby and played in 12 of the 13 test this year so far except the USA test against Wales.
Kolisi has been less than impressive on this tour.
He is not the only one, Mostert played every single minute of Super Rugby to the final and he also did not had the impact we used to from the big man.
Marx sits also in the same boat who played over a 1000 Super Rugby minutes as well and adding 8 test matches to that as well.
Youngster Dyantyi played just under a 1000 minutes of Super Rugby this year with 700 minutes for the Boks in the Rugby Championship out of 720 minutes.
The list go on and on, so it will be very important to put a system in place next year where SA Rugby and the Super Rugby Franchises work together.
