I think it's great that the dangers and negative effects of steroids are well publicised and athletes right down to the high school level are aware of them. I just think it's a non-issue if an adult wants to take a risk by using a substance that will generate short-term benefits but may yield long-term side effects. Bigger, faster, stronger, that's what it's all about. Look at all of the destructive behaviors that people indulge in from smoking to drug abuse to alcoholism to gambling to overeating. You can't save people from themselves, just give them the freedom to decide.
It will always be difficult to compare era's. Technology, nutrition, education, and rules change from year to year and decade to decade. In golf, the equipment (balls and clubs) are light years ahead of what Nicolaus used in his prime. 20 years ago in football you could maul a receiver until the ball was in the air and decimate a qb after the ball left his hand. You just have to take things like that into consideration. A-Rod, Barry, and McGuire are supreme athletes whether they doped up or not. To me it's not an issue. Caveat emptor.
