It's wrong to suggest England served up green tops in 2015. The wickets did offer more for the bowlers than what we've just seen in Australia but they were hardly venomous. The Cape Town wicket just played on, which saw 16 wickets fall on what was essentially day 3 was much more difficult with exaggerated seam movement and uneven bounce. Australia, in recent years, have always struggled to face and control the swing of the Duke ball. Unless they master it better in 18 months, they may still struggle depending on what side England put out.
