Probably too small a sample size (ironically given his noted girth) but Warwick Armstrong won 8/10 tests and drew the other two.
Also whitewashed England when such a thing had rarity value.
Woodfull impresses me too; maintained a stoic dignity throughout the Bodyline tour and bookended his captaincy by regaining the Ashes in England twice, which might be a unique achievement.
Good calls, and I'm sure they were both fine captains. In terms of ranking them, Armstrong did have the benefit leading a strong Australian aside against opponents who had been severely weakened by the ravages of WWI, and Woodfull benefited from Bradman scoring about a zillion runs in both series.
As for the others, Waugh suffers from '
Thora Hird Syndrome', meaning that the side he led could have been captained by TH and they'd have still been nigh on invincible. And given what followed, the fact that he never led them to a whitewash over us in our absolute dog days must be held against him. Loved Ponting and still do, due to his poor calls across the 2005 and 2009 series. But my affection for the man doesn't make him a great captain. I can't believe Clarke is even in the list; from memory three Ashes defeats, and behaved like a complete arsehole the one time he was lucky enough to have Johnson turn up. I don't really know how to rank Bradman's captaincy. He was probably perfectly fine, but everything was weighted so massively in his favour that it's hard to tell.
3rd place is between Chappell and Border. Both took over weak teams and took them to near the top of the pile. Maybe Chappell did actually take them to the top of the rankings after they won in England in 1975. I couldn't honestly say. Someone like JBMAC would be fascinating on the subject.
2nd place goes to Taylor, who definitely took them to the top of the rankings, and did so by winning in the Caribbean when that still counted for a lot.
1st place to Benaud. To take that side to number 1 and remain unbeaten during his time in charge was quite something, especially when, man-for-man, the players weren't so obviously superior to England or WI as other guys were able to benefit from.
