So to summarise what I've read here - it appears Djokovic has surpassed (at the very least matched) Becker and Edberg taking into account titles and time at number one.
But there is some doubt as to whether these achievements are as valuable due to posters insisting on comparing eras, conditions, etc - comparisons which always end up as futile exercises in debate.
There is also some doubt as to whether Djokovic can be considered a better, more complete player than either, due to some insisting he lacks skills with his netgame, etc, etc.
Of course, then we have the increasingly juvenile trolling and counter-trolling, descending into name-calling, hair-pulling, bad-repping, and "my country's bigger than your country" nonsense.
To take this further, according to the progression of Fishnet's posts, I think he will next suggest that Djokovic should relinquish all his career achievements for Becker and Edberg to divide up simply because he is playing in 2013 and cannot volley.
