Bernie,
I believe that most likely almost EVERYONE at THAT level of ANY sport is a "user" to ONE DEGREE OR ANOTHER. This has been going on for decades. Just look at the Olympics. There have been instances where government supported teams have encouraged their athletes to be users - sometimes without the athletes' knowledge.
The governing bodies are only setting ARBITRARY standards to limit the bad
PR.
Is ANY use of drugs CHEATING? At this point, I no longer know, since it is so prevalent.
Like I said about Ullrich and Basso, it would be nice to be innocent until proven guilty. Look at say Barry Bonds in this country. Sadly, for the athlete's involved and their sports, even if they are all "innocent", they will be forever tarred with the "where there's smoke, there's fire" brush. Like I also said, I'm glad that I am not the one who has to make the decision on whether or not what an athlete is doing is "legal" or not.
Another sad day for sports, no matter how it turns out for any of them.
"Cheers!"
Dave
