For SA both Bakkies Botha and Jaque Fourie have already called it quits unless they pull a Matfield on us but I'd be surprised if they came back in.
Certainties for retirement I'd imagine (at least from test rugby):
Victor Matfield (37)
Fourie du Preez (32)
Schalk Burger (31)
Jean de Villiers (33)(might bow out not on his own terms if he isn't part of our RWC squad which is a pity)
Jannie du Plessis (32)
Morne Steyn (30)
Bryan Habana (31)
JP Pietersen (28)
Will probably play on in Europe for another year or 3 and might make the Boks still but we should really be looking at our options:
Tendai Mtawarira (29)
Bismarck du Plessis (30)
Willem Alberts (30)
Two years still post 2015 but not another RWC?
Duane Vermeulen (28)
Francois Louw (29)
Adriaan Strauss (29)
I expect our Bok team to look quite different post RWC 2015. This is crystal ball gazing but that is what this thread is for, right;
1 T du Toit 23 T Nyakane / S van der Merwe - upgrades, all three of them
2 A Strauss 16 S Ntubeni - will miss Du Plessis
3 F Malherbe 17 M van der Merwe / J Redelinghuys - upgrades, all three of them, should be starting regularly already but for injury
4 E Etzebeth 18 L de Jager / F van der Merwe - Etzebeth already our encumbant and very young still; hope he gets back to his best
5 PS du Toit / J du Plessis - should bring better mobility and workrate, so upgrade IMO
6 M Coetzee / J Kriel - Coetzee already pushing Louw.. Kriel in super super form
7 A Botha / O Mohoje - Botha should have been playing for the last 1 and a 1/2 years now but for injury
8 N Carr 19 W Whiteley - Vermeulen isn't easily replaced in the form he is in but these two add a ton in the loose
Overall the loose trio is going to be smaller but waayyyyy more dynamic with skillsets too match
9 C Reinach 20 F Hougaard - same, we need Reinach to step it up ITO consistency
10 H Pollard 21 P Lambie - can only improve with experience? Upgrade IMO
11 S Senatla - reminding me of a young Habana but needs to prove himself at higher levels still
12 F Steyn / D de Allende - upgrade on JdV IMO ITO pure playing
13 J Serfontein - same, hope he gets more and more used to the position
14 C Hendricks / L Mvovo - same. I like the look of Kobus van Wyk as well but a white wing for SA?
15 W Le Roux 22 C Kolbe - same but if Willie can't get his error count down then boot him IMO
Overall good continuity.
