I would love to see what the Re-Union panel say about Goosen and the Springbok performance - but the programme is only on on Wednesday at 18:00. You are in all respects correct about Carter - but he is on the old side of fkyhalfs at this stage and Goosen is by far the youngest international flyhalf.
The game on Saturday would be particularly interesting - but I think the SA defenders will try and isolate Carter and the All Blacks will evidently try the same tactic. If Goosen comes through the test on Saturday through a repeat performance like he did against the Wallabies - he is really destined for great things in future.
