So dont you think that used properly as a 5th bowler, as Kallis is that his stats wouldn't have been better? Look at his economy rate, that was his primary job, and if you actually read about his medium space swing bowling when properly rested then you would understand. He was an over worked all rounder pressed into service as a strike, second change and when required spin bowler. Such was the work load of the man, and those who actually watched him, realised that.
And just for empasis name a genuine #6 batsman who comes close to Sobers as amatch winner in the 3 areas. Kallis batted for him self and begged of bowling when ever he could. Thats why Sobers is seen as the best by a mile.
You keep framing the discussion as if being the greatest all-rounder of all time is dependent on the fact of being a great #6 and someone who could bowl a bit. If the greatest compliment you could give him is that he has a good ER then the discussion should be already over.
The reality is that the stats don't match up with the stories. EVEN if we consider his overall record one where he was only a pure spinner...it still is not even as good as the average spinner of his time. You know what that means? It means the dilution of his record as a pacer should at least improve his figures to that of the average spinner during his era if he was in any way half decent as a pacer. Yet it doesn't.
There is one counter to the above argument. That is: he was so very crap, garbage, bad as a spinner that his great pace bowling still couldn't fix his overall figures and what they are right now is actually very good considering. However, this is such an illogical position because asking someone who is
that good as a pacer to improve his overall figures
that much
inspite of his spin bowling to bowl spin is akin to asking Marshall to bowl spin.
But that not only doesn't match up with the commentary of his bowling, it doesn't match up to plain old common sense. Also, as I've already mentioned, Sobers bowled with at least 1, sometimes 2, recognised spinners throughout his career, as well as many other all-rounders. He bowled a hell of a lot, changed up his bowling too; but not because he was some martyr.
FTR, Kallis' bowling is better than Sobers.
