It is already fading. Been fading for years in the USA. Economically, tennis doesn't make sense for most people. Years ago, a retired player could coach and make a fair living. With the game dropping in the U.S., those prospects go with it. It is a great game, it shouldn't be this dire. Yet, I live in Florida, and curling is on the rise here. Unreal.
The Roddick, Fish, Dent, Blake and Ginepri group was really the last U.S. tennis was even fairly represented.
