Fun fact: if this does happen (he gave up on defending himself SOOO), then 9 of the last 15 Tour de France titles will be stained by doping. Woo yeah!
But it gets better- a good amount of runner-ups are also suspected of doping so, if they start rechececking the blood tests, they'll have to give the titles to the 5th place rider or something. It's going to be very fun.
Banning him from future events would be like banning George Bush from running for US president ever again because of the 2000 shenanigans- nobody is going to notice a damn difference with how the world was the day before.
