Anyways, I'm not sure tennis has any interest in exposing top players, especially great champions. Who watches cycling without Lance Armstrong? No one. For tennis to lose a couple of the big names at the top would be a huge blow- the whole organization of tournaments etc is to benefit the top seeds.
Exactly - and this is why I'm sure there'll never be any doping scandal involving a top player in tennis ... The powers-that-be will make sure all evidence is conveniently swept under the carpet and they'll reach a compromise with the player ( silent doping ban etc...)
They're focused on keeping the sport profitable, not clean...
