OPINION:
There is nothing courageous or heroic about Cameron Smith taking painkilling drugs just in order to take the field in the NRL Grand Final. And the sycophantic Ozzie sports media falling over themselves to fawn all over him need to stop the butt-kissing and start doing their jobs - which is questioning the legality, morality and long-term sensibility of both his and the club's actions.
For a start, what kind of message does this send? The idea that any athlete in any sport is so busted up they can only play after injections questions the integrity of both athlete and event.
Smith's injury was/is so severe he can't swing a golf club - meaning HE CAN'T PLAY, or he can't play without having to have painkilling injections i.e. drugs. And if he can't perform without these drugs then by definition they have to be called performance-enhancing.
To me, this is in the same department store as Lasse Viren's blood doping. It's putting something into the body that means the athlete transcends the level they could or would ordinarily perform at that time.
