Mvovo, Habana, Willie, Hendriks, JP: 5 players for 3 positions

These are 5 really great players. 
Mvovo is in the form of this life and has really blossomed under Jake White.
With more pressure to play indigenous players by the sports minister, their might have to be a place for Mvovo. Although who would you drop.
1. Habana - the best wing in the world
2. Willie- The form fullback in World Rugby. Folau is also great, but Willie also brings a playmaking ability to slot in at 10 on multi-phase possession. He is not just a finisher and also creator
3. Cornal Hendriks- who has proven he belongs at international level in the 15 man code. Give him space and he is going to score.
4. JP on the wing (If Jaque Fourie or Delande takes the 13 spot, JP will again be a contender for wing) 
5. Mvovo. Probably as fast as any wing in the world. He converts oppertunities into tries at will. He is a classic winger that will punish the opposition on any mistakes they make, and convert attacking oppertunities into points and pressure.
Plus, their is JP at 13 who had his best game as a centre today. Lots of good breaks cutting the line, lots of good running lines and passing- and creating tries etc.
The Boks actually now have lots of depth in many positions. At lock we have a ridiculous amount of depth, especially number 4 lock.
We have great depth at inside centre, even with Fat Steyn.
At scrumhalf we have FDP the best in the world, plus some decent cover like pienaar and hougaard, plus players not even in the squad.
we have the 2 best hookers in the world.
Our props are concerning especially at tighthead, we need some better players. Coenie seems to be struggling at scrumming and Jannie is often just a passenger.
Loose forwards are usually fine in South Africa with lots of depth
We are a bit short in specialist 6 fetcher, but it is pretty good. 
Schalk has added some speed and skill to the backrow in place of Fat Albert who is better in the northern hemishpere.
Flyhalf position is looking good with Pollard surely the number one choice. If Goosen can build confidence from not being injured so often, it will be 2 world class flyhalfs. Then we have Bambie, and perhaps Morne. 
Inside centre is great with Jean, Delande, Jan, and even Fat steyn if his contract issues are resolved.
Outside centre is ok.

I agree with you.  Despite his better showing on attack yesterday Pietersen's defense was extremely questionable and I am still convinced he will be better on the wing than he is at center.   
The problem is that the backline playing yesterday showed speed and fast attacking ability.   Pietersen showed reasonable  speed in the case of the dribble kick leading to Mvovo's try - but he was put into space by Pollard and the opposition players were catching up with him - hence the dribble kick.   His own try showed strength - but no real speed.
I also think that the problem with Fourie is his serious lack of speed and his recent lack of showing anything in attack - he is primarily a good defender nothing else.  I would rather see a center combination of De Villiers and De Allende - with Serfontein as back-up.
As to the wings - I think that Habana and Pietersen is the likely combination - but would rather see the Habana and Hendricks combination - since both has speed to spare.   I would say that for the RC the wings should be Habana and Hendricks with Pietersen on the bench.
