The pundits are saying the All Blacks look weak under the high ball. So it is likely we shall see Pollard starting to play a territory game of keeping the All Blacks in their half as much as possible. Grant Williams is the Boks' best box kicker since Fourie du Preez, so there will be good kicking options.
Sasha will almost certainly be on the bench as a utility player. We could see Sasha replace Delande at 12 during the game, or 10 to replace Pollard, or to fullback. The Boks will go wide, but it will probably only be when there are overlaps, or in periods when the Boks dominate rucks.
