South Africa will have to fight hard for this one.
NZ are the slightly better team on paper; but only in terms of depth. In almost any team they field, they have 11 pretty good players. SA has a few superstars, some of the best all rounders in the world, one or two of the best bowlers, and a few of the best batsmen. Not quite Aus, but we're working on it. What SA lack is consistency, and a team of 11 decent players (normally only 6,7; with the remainder made up of sometimes on, mostly off all rounders).
Add to that the bad blood between the two teams [with some black cap antagonism in the last series, and South African short-sightedness, and schoolboy antics in response] and you have a series red hot and ready for the anvil.
Boring ... Damn me - this is going to be hotter than anything cooked up on the sub-continent in ages. And it aint going to be one-sided like almost anything involving Aus, or indeed as dull as most of what England produced prior to the Ashes.
Two of the best teams, fairly evenly matched and looking for blood.
