The most memorable moment of the Tokyo Olympics may have been a star athlete’s decision to withdraw from competition.

Billie Jean King standing up to unequal treatment of female athletes. ­Muhammad Ali rebounding after banishment from boxing. Tom Brady silencing the naysayers, again and again and again.
