All its former teammates have been alleged of using drugs.
We're not talking of vulgar EPO, basically, in sports, only the ones who use cheap, last generation drugs get caught. If he has not been caught, it's because he was taking something undetectable at the time he was running. Everybody in this little world knows that. The only thing is that he is a symbol.
What bothers me is that in this sport, everybody knew he was winning cause he was cheating, look at cheaters who were behind him.... it was a secret to no one but those who were believing the fairy tale of 'he was better'.
Now that he has been officialy stripped from its titles, means that all the other one can now claim for victory and prejudice... Also, this can lead now to real investigation, now that he won't be protected by an army of lawyers...
Nonetheless, that does not mean the other sports are clean, take rugby, football.. it's just that nobody cares to stir the shit too much in these lucrative sports... Even tennis has its own agency for testing, and decisions against those who are caught cheating are done 'internally' so that it does not cause major shitstorms in medias...
