Completely agree. For what it's worth on the less-debated elements of the original post, Pollock RG was a true great of the game. Donald still beats Steyn - his average is a point lower isn't it?
Now... Kallis vs Sobers.
I'm a kiwi/Brit and have seen Kallis do well against NZ a few times. Saw him bowling in the World Cup in '99 when he was seriously quick and seriously good. But....
1. His minnow-bashing is absurd. 80 with the bat, 15 with the ball. It almost looks mean-spirited...
2. My perception is that there was a time when more than once, SA were well ahead but he never tried to accelerate at times when quick runs to set up a declaration were needed. It felt like getting his average over 50 was a huge thing for him. This is a few years back, I agree he's a more attacking player now. But still, you suspect Sobers wouldn't have known his batting average to the nearest five runs...
3. Sobers was a front-line bowler in over half his tests, Kallis was a fourth bowler. You can have a decent debate about which is the harder role. Sobers got a new ball quite often, fresh wicket sometimes. But the workload was much higher. Kallis got an older ball, occasionally set batsmen. But Kallis also often bowled a couple of overs, if nothing happened, he'd be off, and he also seems to have had a lot of days where he's got to knock over tail-enders (last week being the latest). A bad day for Kallis was none-for-forty, which has protected his average in some ways.
4. South Africa, I think we can all agree, have underperformed in the past 10 years. Given the players they've had, they should have won more test series, and they should have been a tougher opponent for Australia (especially at home). Kallis, possibly through no fault of his own, has been a big part of that, so I feel he'll never get the recognition he deserves because the side hasn't done as well as it should have.
5. Finally, Sir Gary was a true globetrotter. His image is of a guy who played for fun. He went on all sorts of "international xi" type tours, played for the Rest of the World, delighted county fans in his stints at Notts. (Yeah, I know he probably did this for money, just like everyone, but still, I can't imagine Kallis giving up his off-season break to go to Pakistan for two months on a tour.) He could drink most of us under the table then turn up at the ground and make a hundred. He bowled seam/swing, finger spin and wrist spin. He was a fantastic fielder. He made crazy declarations as captain. His batting was poetry in motion (possibly because he had that left-hander's natural grace?). Kallis, though technically sound with the bat, and occasionally menacing with the ball, and very good in the slips, just really never ever sets anyone's pulse racing.
I will always freely admit that Kallis's stats make him one of the top two to four allrounders ever (along with Sobers, Imran, and Miller for me, with Procter in a "maybe" category). But I don't think I could ever rate him as number one.
