Raval and CdG will struggle against the seamers. Latham can go either way and Ross really is due to rectify his record vs SA. Kane will be fine and Watling seems to be regaining some form at least. Santner could go missing and if Nicholls plays, I think that's anyones guess because I'd hazard he'd fail but then he did well against the Saffers in their backyard so ???
I think South Africa probably have a 60-40 edge on us, and 20 of that 40 for NZ is based on home conditions, really.
The tiers of players for mine at this time
Taylor, du Plessis
de Kock, Bavuma
Cook, Elgar, Watling
