Amid the Brearley-vs-Lloyd thread several interesting questions are raised. So I feel it best for a separate thread discussing not two but many great cricket captains. I don't include Stephen Waugh or Clive Lloyd as I don't feel either were particularly good captains - and Allan Border is included with great hesitency too. But obviously they will receive their share of discussion.
I post a poll for people to vote for who they think best - but as I say, the idea is not really about who's best, but trying to establish why those who were good were so good.
