He admitted to doping for all 7 tour victories.
I am of two minds on the issue. He broke the rules, which is not ok. At the same time, if your sport has an unenforceable rule, you either need to reevaluate your rules, or develop some way to enforce them.
Furthermore, he has done a lot of good outside of his cycling exploits. For example, half a billion dollars for cancer research. Thoughts?
