Top 4 are very close...
For the World Cup next year, it seems almost certain the winner will be one of these top 5 teams.
Can't see any of the other teams beating Top 5 opposition 2 w eeks in a row, let alone 3- assuming they draw a top 5 team in the quarters.
The Boks will not win unless their attack improves. With Libbok, the potential to keep expanding the running game is possible, but not if he is getting splinters on the bench.
At this stage, only Libbok and Pollard are contenders for the flyhalf match day squad.
Pollard can play at the centre as well, so has utility value.
Zulu did not get experience on this tour, other than the b-team disaster so it is probably too late for him.
