Ponting better to watch. Kallis the better batsman. All this "selfish Kallis" stuff really is crap. Would you prefer him to be wafting outside off-stump with lazy airy-fairy shots because "that's the way he plays"?
He wasn't in contest with all of them at the same time though, was he?
Hall, Griffith, Davidson, Gibbs, Valentine, Benaud, Mckenzie, Lindwall, Miller, Snow, Underwood, Bedi, Prasanna, Chandra, Lillee
Which is surely more relevant when trying to determine the impact on his bowling ranking. Whilst, the list provided of Kallis' 90s contemporaries:
Donald, McGrath, Pollock, Wasim, Waqar, Ambrose, Walsh,
They would have been direct competition for bowling rankings at the same time as Kallis' bowling peak.
Lillee, for example, is a complete irrelevance as by his debut in 71, I doubt whether Sobers was reasonably at his peak. He took 40 more wickets over the remainder of his career post 1970.
