I think there will be some halftime changes made - like moving Willemse to flyhalf and bringing on Le Roux to replace Willemse at full back. Reason we need cover for Pollard and at present there is none really usable ones.
Kwagga has been problematic thus far and I think Du Toit might replace him rather early as well.
Using De Allende at 13 is another of those changes - he has not played at 13 since 2014 and the back-up position in that position is problematic as well. I think Pollard will also replce steyn ar 12 rather early.
It is also becoming clearer who would be in the quarterfinal team - looks to me that it would be as follows:-
15 Le Roux, 14 Kolbe, 13 Am, 12 De Allende, 11 Mapimpi, 10 Pollard, 9 Faf, 8 Vermeulen, 7 Du Toit, 6 Kolisi, 5 De Jager, 4 Etzebeth, 3 Malherbe, 2 Mbonambi, 1 Mtawarira
16 Marx, 17 Koch, 18 Kitshof, 19 Snyman, 20 Louw, 21 Jantjies, 22 Willemse, 23 Nkosi,
