rankings are not as bad as you think..........Fingon said:I don't think there is any relation
YOu can't predict a player's career based on what others achieved, each player is different, the circumstances are different.
Some players develop early, some later (look at Dominque Van Roost, Testud, Tauziat that have their best rankings at the end of their careers). Some styles need more time to mature, some less.
Players might be not too committed when they are young and work harder later.
Some players learn to win when they are more mature, some do it earlier.
And the competition has a lot to do, the ranking is not only up to the player (except in the case of Serena ), and it also will depend on how weak or strong the rest of the field is. A player can face a strong field early in her career and a weaker one later and then climb in the rankings.
However, you can tell (with a big margin for error) if a player is top
ten material early in her career by watching her play, but not by the rankings.
A player can be losing all the time because of mental problems, or because she needs to work on parts of her game but she can have great skills and then there is hope she can eventually start winning.
If the player doesn't have a good game, it's probable that even if she achieves a relatively high ranking early she won't go much further.
And also remember you can't compare with players that didn't go through the AER.
