I know others here look at years moreso than test matches played but I measure career based on the latter.
And by that reckoning it doesn't matter if I start at 80 or 82 because you will still end up with a larger share of Imran's career as a quality bat than Kallis as a test standard bowler.
And no, Kallis doesn't have comparable numbers, even in his supposed bowling peak.
This is Imran's full batting peak and you can dance around it and pretend it's inflated but he outstrips Kallis pretty comfortably in his second discipline.
