Giambi's admission to the grand jury (leaked to the SF Chronicle) will shoot a giant hole in the theory that it takes more than brute strength via performance enhancing drugs to hit homeruns. The argument often cited has been hand-eye coordination.
Not anymore.
As A's fans;
JUST ACCEPT AND MOVE ON.
Will Carroll will be weighing in at Baseball Prospectus at some point and ALL of the sports talking heads will be coming out of the woodwork in the next 72 hours. I'll try to point you to as many fact-based articles as possible. But, I do not want to get involved in the argument or the debate.
Performance enhancing drugs were not against the rules in MLB because MLB did not have a policy. And even so, "if you're not cheatin' you're not trying." Further, steroid use and use of performance enhancing drugs has never, ever been the issue. The abuse of the products has always been the issue and that has never been brought to light.
I think the health risks were made clear in the last two years by both Giambis. Jeremy's injuries and Jason's injuries, while not 'directly caused by steroids or performance enhancing drugs' are enough to scare most away from regular usage.
