There is a reason we are conducting this voting, and not copy-pasting from an 'experts' list. Is there? If not, why are we?
By the way if we are basing our opinions on experts ('notable judges', as you say) then what do you think when Sobers says that Gupte was a better spinner than Warne? Or, when Hutton says that Gavaskar would be as famous as Bradman had he been an English or an Australian? Or, when Sobers says that Gavaskar is the best batsman he's seen? Or when Bradman picks Arthur Morris in his all-time XI? Or, when Warne keeps Waugh at no. 14 (?) among his Aussie teammates? Or when Dravid says that only God could be better than Ganguly on the off-side...
It seems very hard to make you understand the word 'honesty'. You would never know whether I am being honest while making my list. Only I would know. And this kind of a voting will work only if everyone is honest - not if you deliberately vote the other way to 'counter' other voters. If you think like that today, tommorrow I might vote for Ganguly at no. 1 to counter Jardine, and day after Jono will bring in Kohli ahead of Bradman...that's the way World War III starts
