Tendulkar, Lara, Richards are cricketing royalty and so is Kallis - yet too often he is forgotten like Prince Philip the Duke of Edinburgh and, let's face it, Old Phil is pretty close to the top.
Maybe it's because Sir Viv was the Master Blaster, Lara had that flamboyant style and a penchant for massive totals and Tendulkar a style so often compared to the great Bradman himself but also promoted as 'great' from age 16. As for Kallis, well he has just plonked himself at the crease and churned out runs.
Could it be that South Africa built itself a batting machine and just wanted to keep it a secret?
This could be Kallis' strategic advantage; he is so efficiently boring that no one can quite work out where to bowl at him.
I'll tell you who is not boring - Graeme Smith. He's one of those guys who seems to be very unpopular with the opposition. I believe that to be because he plays the game with his heart on his sleeve and refuses to take his place on that hoity-toity world captains' table.
He has 7760 test runs at 49.42, with 23 hundreds. That suggests he's one of the best test openers but it's his grit that impresses. The Kiwis will try to get inside his head - everyone tries.
But, good luck. He's led South Africa since he was 22, he's now 31 and I imagine you'd need to be not only headstrong but also politically savvy to lead for so long in such a political environment.
The century he scored in the third and final test in Wellington the last time South Africa was here to square the series will always stand in my mind as one of the grittiest and mentally strong innings I've witnessed. Smith is one of my most admired cricketers but I guess, just like him, I go against the grain.
