C. Rochus wasn't bullshitting, there really is doping in tennis.
What's amazing is the denial that's gone on for so long, the protestations of a clean sport ........ and the conscious decision at the top of tennis to do basically no testing. They make even a tiny shift towards better testing (and it really is pretty small, it's still nowhere near where it needs to be), and bang, multiple test failures.
I think perhaps Fuentes and Biogenesis have opened the eyes of the upper tennis hierarchy, and they've decided to start cleaning house. Baseball is probably the model - they left it too long, and now suffer the consequences of an entire generation looking like dopers.
Certainly should make tennis less predictable at least. All those big names getting "injured" or losing early because they can't dope, really will open up a lot of events.
