Boucher in at #5... bit if a concern, especially considering they opened the batting with an allrounder. They basically only played two specialist batsmen - Ashwell Prince and Graeme Smith. Kallis effectively makes it three, but really, too many bowlers.
If they plan of picking such a bowler-heavy side, they should at least pick a batsman as the super-sub. Robin Petersen isnt going to accomplish anything regardless of whether South Africa bat first or second. If they bat first, and he comes on in the second innings, he'll be 8th choice bowler, behind Pollock, Ntini, Nel, Langeveldt, Hall, Botha and Kallis. Not a great chance of him bowling, really.... and if they bowl first and he comes on in the second innings to bat, he'd bat at 8. Definately a waste of a position that could have been supplied to De Villiers to back up the batting.
