This isn't really that uncommon of a viewpoint.
However I really don't understand it, and I find it such a stupid, not-thought out opinion to have.
Sure you can have dudes roided out, especially if MMA is to remain a niche sport , but crossing into the mainstream, it'd look like a joke and a sideshow.
Look at the disgrace that baseball suffered when they went through their steroid era, it looks terrible in the public eye and relegates the sport to a circus attraction.
It's hard to justify a mainstream sport, one that's supposedly one of the safest sports in the world(according to White) one that's supposedly safer than boxing, and dudes have to inject roids to be competitive. How's it going to look when former fighters are dropping dead in their mid 50s because of the lifestyle of steroid abuse and fighting way too long in a sport where drug use can prolong your career.
