These young guys need time to develop (mentally, physically) There's too much pressure and media put on them. Roddick, Blake, Federer. They'll win a Slam when and if they're ready. And they're all improving, especially Blake just in the last year. Not everyone is going to be a Hewitt and win a Slam by the time they're 21. Anyway, someone said not too long ago that both Agassi and Sampras won most of their Slams after the age of 25. Patience!
