Conjecture, and only that ... bringing Serena into this mix, isn't fair to her, or anyone else for that matter.
AFIAC, Lance did -FARRR- more (damage) then just taking a pill, he (and his assigned posy) defined and regimented practices with the CLEAR intent to cheat, forced THAT on all his teammates, and continually told lies to justify his actions. Never any accountability, little responsibility. The lowest common denominator between all these athletes is simply the drugs ... that part is all too easy related. The rest ...
I don't think it's conjecture at all. Mary Carillo campaigned for Serena Williams' suspension for threatening a referee. She was punished on the spot with loss of point which cost her the match. I agreed with the punishment. I did not like it.
Imagine if Serenas' power game could be associated with PED and the firestorm that would ensue.
I have no idea what it is like to spend your entire childhood being told you are going to be the best player in the world and then reach a plateau short of your goal.
