The first one wasn't a green top by any means, flat flat flat. Durban can be tough, but can also be a road. The fourth one was certainly not flat, dunno about a green top, some very average bowling though (plus it was Pakistan). The 3rd one wasn't a green top, just usual day 1 movement, SA got themselves into a hole and Kallis played a good knock for sure, but not a masterful green top knock. The 2nd one is a decent example, but only 1 out of 16 years? Hardly constitutes mastery of green tops. You claim to have watched all his innings too, I'm not trying to be an ass, but until just recently no-one could name many great Kallis innings from the previous 15 years, he was well below on the great batsmen of his era, but now that Lara has retired and Potning out of form Kallis has risen up based on his 2 innings vs India, and we know how badly they bowled this whole year.
