Well, firstly all the other things you mentioned are not against the law, like steroids are.
Secondly, why I agree that steroids wont help you hit the ball, they will help you hit the ball harder and further, perhaps turning fly ball outs into home runs.
What's legal is entirely arbitrary. Why steroids should be illegal and cheating but taking a ligament from one arm and putting in the other is normal medicinal treatment is just completely arbitrary.
Even so, it was only in early 2005 that steroids became controlled substances.
Through the 2004 season Barry Bonds had clubbed 703 HR and he has not tested before or tested positive since.
What exactly did he do wrong other than annoy the media?
Steroids making balls fly farther is a myth. To the extent that it helps at all, it is to such a small degree that it is meaningless.
More likely the surge in HR is due to a changed approach at the plate, particularly as Bonds changed from a more speed oriented player to a slugger.
From ESPN:
"From 1987 to 1998, Bonds' average ground ball to flyball ratio was 0.81; between 1999 and last season, it was 0.62 -- an increase of about 19 extra flyballs for every 300 balls put into play."
Not this argument again, its been proven that roids help with a swing by speeding up the bat. The health risks alone should be a good reason not to use it. Fixing ones eye site or getting surgery to repair what was broken is not the same as pumping your body full of chemicals to get an unnatural edge.
Really who proved it? If it's that simple, one link will do.
Most of what steroids do is recovery. How is recovery on a day-to-day basis -- the recovery from micro injuries -- any different than a massive surgical intervention?
How are chemicals, many of which are completely natural and occur in your own body an unnatural edge but taking machines to transplant a ligament or shave your eyeball is normal?
Even if the steroids in question are artificial, that's no different than using artificial means to repair a rotator cuff or a broken leg.
Nick Johnson the injured 1B for the nats broke his femur and has titanium in his leg. How is that "natural"?
Isn't him using titanium an unfair advantage over people who didn't have that option?
Think for a minute, the illogic detector is going off.
