as far as needing a "squeeky clean" bb'r to be "good" for the sport, image wise it does nothing.... good does NOT - $$$$ so..... what about controversy, must do well because mainstream media uses it all the time to sell products so... good really = $$$ whats good for the image may not be the same as being good for the wallet. wrestling made about 1.75 biliion dollars from last years wrestle mania, all the show in bodybuildings history may have not even come close to that number, Bodybuilding needs to take a page or something that resembles a page out of wrestlings book. guys oiled up in thongs with muscles prancing around on stage is not cutting it, even if they were articulate ( because some claim ronnie is not which is reason being for his "lack of mainstream success")
the sport needs more. no matter what people/public will see bodybuilders even if they are natural, to the public it doesn't matter because natty or not they are all steriod users. finally you have a guy willing to admit it (steroid use) and does not lower his head about it. everyone gets pissed at guys that say they don't use steroids or even better the guys that use but only 12 weeks before a contest (yeah right). now enter gregg, who lets you know he used crazy amounts but no, there still has to be more. it's crazy, if he let you know that much it wouldn't be worth hiding anything else, he's not trying to look good he is just telling the truth.
Considering bodybuilding is a pastime of aesthetics putting Gregg in the media selling bodybuilding is a bad idea. Opinions on what is aesthetic vary but few would say anything less than Gregg looks like a complete fool.
You might consider Gregg to be a good fellow and I'll bet he's an interesting person to talk to but in the context of saying he is positive for bodybuilding he is absolutely not. Like I say (which you ignored) - Gregg advertises an ugliness gained from bodybuilding that is akin to seeing an amputee victim caused by bad injecting technique.
Nobody who looks at gregg thinks the guy gets a lot of ass for his appearance. He's not selling shit but the fact he's a freak and whilst its perfectly cool that he is doing so you are talking complete and utter bullshit when you imply that he is having a positive effect on the public perception of bodybuilders. If you were 12 years old and you saw that guy with those stupid arms (and they are stupid, they look like blobs) you wouldn't want to be him in a million years.
Envy is a huge part of marketing, selling the romance of "being the star". Haha, I could probably count the number of people who would strive for those arms and thus be enthused by him to bodybuild on one hand. At the very MOST seeing gregg on tv would not do anything to motivate a person towards bodybuilding. At the worst he would be sending people the opposite way.
So in summary, good person? who cares. Good ambassador? Absolutely not, no matter how cool he is to talk to. Would you sell matches with a silver tongued burn victim?
