That's not what you said originally though.
The question put to you was would you rate Sehwag as an ATG if he plays another 20 Tests in which he averages 70, including fixing his record in South Africa?
To which you answered no, because Ponting is more versatile with a better technique. What on earth leads you to that conclusion if Sehwag fixes the only real hole in his record?
Because according to the above post succeeding in South Africa would show that Sehwag's technique is sound
One feels you're being a little frivolous with your definition of technique. Is it "conducive to versatility" as you've suggested? Or is it something separate, such as being able to play the swinging ball and a lack of foot movement? Which alludes itself to the point I was making about scoring runs despite his technique, rather than because of it.
