Sobers, great batsman, all round bowler who could bowl medium fast, off spin and leg spin. I think from memory batting was in high 50s and bowling mid 30s. Rated as the greatest by many as he could arguably hold his place in a test side as a batsman, paceman, leg spinner or off spinner.
Khan and Miller. Khan shades Miller statistically, both had flair, personality, dash. Pakistani's argue that miller played in an easier era with regard to bowling and often against an england damaged by WW2, Australians argue Khan's statistics are edged out due to home town decisions. Definitely an argument for the ages. For me, its miller, because he lost years to WW2, kicked 9 goals from CHF, represented NSW and victoria at AFL and cricket, could play tennis, bombed berlin, screwed 1/2 the british nobility (according to legend), did a fly over Beethovens birth place after bombing berlin, stuck his nose up at authority and frankly the brits had to invent hero's like him. Certainly did some 'bad' things in his RAF career and cricket career but then it adds to the legend IMO.
Kallis, started off as a lower middle order batsman with some talent who could bowl at 150kmhr. Back injuries curtailed his bowling shortly after getting 150 wickets, and he was little more than a Jeff crowe trundler for the last 7-8 years. His batting has flourished and while he lacks any flair with the bat, his stodgy scoring has been the backbone of the the RSA middle order for a more than a decade. Again in an era with more than a dozen batsmen averaging over 50, it detracts somewhat, plus plundering the zimmers and bangers regularly. His bowling average has slid up from 25/26 to 32/33 over the past few years from being the first drop after an era of donald, ntini and pollock, to plugging a few overs here and there.
Beefy Botham, averaged in the mid 30s with the bat, and high 20s with the ball (again from memory) his career went up and down with responsibility, booze and his own delusions of grandeur. A bit like warne, his legend is bigger than him. Performed well in spits and spats during his career with the bat, but always a solid and sometimes dangerous medium fast bowler.
Vetorri (captain, best batman and best bowler of NZ), Dev (adequate accumulator of wickets who once held the record for the highest ODI score with 175 I think?), Hadlee (great bowler who could bat), Pollock (father (batting /bowling) and son (Bowler who could bat) Akram, Cairns (lance and chris, both bowlers with some big hitting lower order batsman) are others that come to mind as all rounders.
