RE: [Blog] Houston We Have a Problem: The State of American Men's Tennis
Riotbeard, I think there are two levels to this - the depth of players (as represented by number of Americans in the top 100 and 50) and the quality (as represented by number in top 20 and 10). The the decline of depth makes more sense with regards to the broader international pool, but what is particularly disturbing is that US hasn't produced a Slam winner since Andy Roddick, and a multi-Slam winner since Courier, Agassi, and Sampras.
Of course all-time greats don't grow on trees, and since Sampras and Agassi there have only been three or four (depending on if you count Murray), but what is different now is that for the first time in Open Era history - there hasn't been an all-time American great playing (since Agassi retired in 2006), or a near-elite American (since Roddick declined and retired). As far as I can tell, for the entire span of Open Era history the baton has been passed, until recent years.
Actually, this just gave me an idea for another chart!
