So, it's funny that when the argument suits you, the pitches become flat and thus the batting averages undermined. When the argument suits you the bowlers, who have taken wickets in the era of flat pitches, performance get undermined due to average batsman.
You'll find that Steyn in the 2007-11 period had to contend with batsmen of the calibre of Tendulkar, Dravid, Ponting, KP, Sanga kind of ATG batsmen. Then you have the greats such as Laxman, Sehwag, Younis, Jaya, Chanderpaul, Clarke who he has also played agianst. He has definitely proved his mettle against the best.
