Eng: V Richards. Dravid and Waugh are good contenders, but i am ruling out Waugh cause during his peak, he faced some of the worst Eng attacks ever. In case of Viv and Dravid, Viv never had a bad series there, his best series was bigger and against a better attack than Dravid’s, and had a excellent tour in 1980 where he faced peak Willis and Botham(on par with Broad and Anderson in 2011) tho not as good as Dravid 2011. Both had a decent tour(1991 and 1996), an ATG tour(1976 and 2011). Dravid had a great tour(2002) whereas Viv had an excellent one(1980), but whereas Dravid had a bad 2007 tour, Viv had a decent. So because I would rate Viv’s ATG tour above Dravid’s, it would be Viv for me, but still close.
Eng: Alderman. Better spread across venues and did it for more matches than Murali.
Aus: V Richards: Very marginal with Sachin and Viv, cause they followed a nearly identical career trajectory during series in Aus, but will go Viv, because his 1979/80 series was against a better attack on tougher pitches vs Tendy‘s 2007 series. Otherwise Tendy 2003= Viv 1984, Tendy 1999= Viv 1988(Viv averaged 10 more and scored much faster, but Tendulkar faced a clearly superior attack tho Warne was from his best), Tendulkar 1991/92= Viv 1975, Tendy 2011= Viv 1980/81.
Aus: Curtly Ambrose. WPM of 5.5, a decent number of matches, consistently great in all the tours, average under 20. Hadlee has even more insane figures, but the Aus sides Hadlee bowled really well to(especially 85/86, where he took 33 wickets in 3 matches) are clearly inferior in batting to the sides Ambrose bowled to(88/89 was a decent Aus side, and the 91/92(which was his best series) was properly good and 96/97 was the best team in the world(and he bowled well to them too)).
India: Lloyd. Dominance in all 3 tours, averaged what 75 for 1000 plus runs. Dominated one of the most deadly spin combos in history on their home tracks, and Kapil Dev and Co for good effect too. Dominated for more the double the number of matches that Younis did for(with similar stats), and Lloyd’s dominance is spread across 5 different tracks, while majority of Younis’s runs come from two tracks(which Lloyd played well).
India: Steyn. Has slightly better stats than Marshall(better WPM, better average, better SR did well in both initial tours, third tour just bowled in one match, otherwise his stats would look even better). Also Steyn’s performance in 2007 tour and 2009 tour jointly is statistically equal to Marshall’s 1983 tour(Marshall had perhaps marginally more competition, but Steyn also competed with Ntini and Morkel), but the batting lineup Steyn faced was one of the greatest in history. On raw stats Walsh is better, but Steyn faced batting lineups eons ahead of the ones faced by Walsh(especially the one Walsh faced in his best tour). Walsh had little or no competition or both tours( no Marshall, no Bishop, no Ambrose). Plus unlike Marshall, Steyn didn’t have a bad series in India, just a one off bad match. So I would rate Steyn marginally ahead of Walsh.
SA: Kohli. Clearly ahead of his competition. Faced even tougher attacks than Tendulkar and Waugh, and in even worse conditions. Faced peak Steyn-Morkel-Philander in 2013 and nearly had a Tendulkar 2010 level series(268 in 2 matches vs 326 in 3 matches), and faced peak Philander-Rabada in 2017-18 with Morkel and Steyn(though not at their peak) thrown in for good measure on some horrific pitches and was heads and shoulders the best batsmen in the series. Doesn’t have a single bad series in SA(was decent, not bad the last time) unlike Tendulkar in 1992-93.
NZ: Wasim easily
WI: Waugh, slightly over Amarnath because of more consistent greatness and because of his hand in 94-95 win against peak Ambrose-Walsh. It is close because of Amarnath’s magnificent series in 82-83 against the quarter away from home.
WI: Imran. Has better WPM than McGrath, tho lower average(probably because he was outright leader of the attack). But bowled to a clearly better batting lineup overall than McGrath(especially in McGrath’s best series in 99).
SL: Lara
SL: Warne
Pak: Sangakkara. Yes he played his best series vs them in UAE(although was good in Pak also), playing Ajmal would have been tougher in UAE than in Pak, so instead he would get extra points for that.
Will take some time for the other countries.
