Well, than kgod this is all hypothetical because we can not afford to take a whole bunch of newbies on a tour. A good "team" with cohesion is always going to beat a "side" full of good individuals and taking too many newbies at this stage will be as good as when we used to fly "A" teams out of SA to cotton wool our starters. Unfortunately, at this stage in the comp, we have to remain pretty much the same and hope to build on that.
SA management has no clue how to blood players and ease them in. If a guy is playing well, the country calls for him to be thrown in, eventually the coach can no longer ignore the calls, chucks him in and we all watch him drown ala Taute as 13 which had the hallmarks of being a cherry bomb but in fact was a pop pop! Look how well Luatua was introduced to All Blacks. You can guarantee that had Richie not been available to play, Victor Vito would have been called up to start in Messam's absence. Luatua has been with the squad for a while soaking it in, the time was right to throw him in with hugely experienced guys around him like Reid and McCaw and he is in a position now to challenge Messam for that 6 jersey and possibly actually knock him off his perch. Great player management. SA management is years behind that sort of play!
What I would do is change a few key positions. Changes in bold.
15 Lambie
14 Le Roux
13 Serfontein
12 De Villiers
11 Habana
10 Steyn
9 Van Zyl (Du Preez not available)
8 Vermuelen
7 Alberts / Louw (last 30 mins-Alberts to empty tank in 50 mins)
6 Fourie
5
4 Etzebeth
3 Du Plessis
2 Du Plessis
1 Mtwararira
On the bench. Take some knew guys:
16 Strauss
17 Marcel Vd Merwe
18 Oosthuizen
19 Willemse
20 Louw
21 Pienaar (In case it turns to shit with Van Zyl. Only reason)
22 Catrakilis (if fit by then) otherwise Zeilinga
23 Engelbrecht
I dont know who I would play at 5 but definately not Kruger. Way to soft for a Bok tight 5 spot. I want a hard man there. Is Bekker not available? Who is hard and savvy enough to call the Bok lineout?
Take a new flyhalf. We have enough in Lambie to cover Morne if we really need but a good 5 to 10 mins at the back end of a test match or just being in the environment want hurt a guy like Catrakilis or Zeilinga. Both have huge future's. Zeilinga has proven himself every level he has played at! He has what it takes I reckon.
