Old players getting picked

Do some players get chosen for the Springboks purely because they have played for the team previously? When a Springbok team is chosen you will often see many names which you have seen before and that would make sense as you would assume they are the best. This is in fact not always the case as it is not always possible to be in form all the time. This is the argument currently of the Springbok team as some players have been chosen purely on reputation. Morne Steyn for example has not been in the form we know he can in and yet he still manages to make the team. This ruins the competition for positions as players who may be the in form players are not been chosen consistently. Are players getting this "special treatment" because of their previous selection. If you are not performing currently you should be dropped and the in form player be chosen, this will promote the dropped player to work harder to make it back into the team and the replacement player to play harder to keep the place. There should be no automatically chosen players because they have played before unless they are the current in form players. This might be a reason for teams not getting to know each other but players should at least be given the chance to prove themselves.
