And some more oldsters miss in your table :
what about Chiudinelli, Haas, Hewitt, Ferrero ? even Ljubicic.
yes I was wondering about the same the other day :
2009 has quite been the year of the oldsters, which is symbolized by Federer's number 1.
Not sure it will be the same in 2010
However, there are several explaining phenomenons which I noticed :
- generations 88 and 89 are really poor, behind Del Potro and Cilic
- generation 86 has also few very good players (Nadal apart of course)
- and I will also say : generations 83-84 are not good either, which explains why generations 80-82, which were great actually, are still the most competitive.
The fact that generations 88 to 90 look poor will not help for next years for sure.
1991 doesn't look very good either.
1992 generation looks so far the most promising.
But before that, the best players fom generations 85-87 might have a good time, and the players from generations 80-82 might last for a while.
