Unfortunately, it's always the little guys that get screwed.
I think that the tennis drug rules and system and enforcements are just messed up. They're either too strict, too loose, or just not properly enforced. And way too many loopholes. Whether it's Agassi, Gasquet, Puerta, Karantacheva, or whoever, is someone paying attention to the excuses everyone sues?
It is sad that there are pros out there (and even sadder young juniors probably doing it too) who feel they need to resort the performing enhancing stuff just to win. And for those who do the performing inhibiting stuff, well that's a choice too. Something most will regret later.
I'd like there to be more dialog/discussion/education/awareness about drug use, both in sports and our society at large.
Tennis, as a sport and business, always seems to wind up shooting itself in the foot. Whether it's suspensions for petty betting, minor drug offenses by Challenger level players that spark major headlines, or top stars being nailed for drug use, the news almost always seems to be bad.
