Aren't you too quick to draw the conclusions? I think you are.
Some random reasons that come to my mind:
#1 - Sampras is considered a great player (except, maybe, tennischick
). What was the time span between his 1st and 2nd slam?
#2 - Are the new balls so bad? How many of them were at Shanghai?
#3 - It was probably the first time that Roddick did someting notable outside the USA and you already call him the "next big thing"? Following your own logic, what are the guarantees that he won't become another Safin (whom you seem to write off now)?
