What was it that allowed that to happen?
Was it the extra bounce? Perhaps it was. The extra rise was clearly worked to the advantage by all the top spinners including Kumble, Ojha, Warne, Vettori, Harbhajan and Muralitharan.
Also, was it the extra 10 or so yards from the batting crease to the boundary ropes? I remember Ian Chappell expressing frustration last year at the bats getting better and the fields getting shorter at the same time. His argument was that by allowing this to happen the cricket administrators were looking for short sighted satiation of the spectators for more sixes (for that is what the administrators can think of as the only love of us one-dmensional cricket fans). The short boundaries were making the spinners lose the inclination to flight deliveries as even the mishits created by good bowling from spinners to top batsmen would regularly go over the fence instead of becoming a catch in the deep. At least the 75-80 yard boundaries in South Africa give tweakers some extra 'ground'.
But someone will need to explain to me where the turn came from. Since their return from exile in the 90's, the SA cricket team were as notorious for their lack of spinners as the pitches in their country were renowned for not supporting them. However spectators got to see some sharp turn in some matches with 6-7 over old balls. And they got that not only from the best spin doctors but also from some of the lesser known (but adequately effective) practitioners of spin bowling.
Did the IPL supremo Lalit Modi manage the impossible of not only taking the tournament from Asia to Africa but also some of the original Indian 'pitch' and tenor within a one month timeframe?
Can't rule that one out, going by the way Modi is beginning to rate himself as a 1st class miracle worker and trying to conjure up bigger challenges for himself.
Arranging 2 IPL's a year, for example!!
