George Will has a good column in this week's Newsweek on performance enhancing drugs and San Francisco Giants slugger Barry Bonds. One paragraph should tell you all you need to know about Bonds and whether or not he used steroids.

According to Mark Fainaru-Wada and Lance Williams, the San Francisco Chronicle reporters who wrote "Game of Shadows: Barry Bonds, BALCO, and the Steroids Scandal That Rocked Professional Sports," Mike Murphy, equipment manager of the San Francisco Giants, testified that since Bonds became a Giant in 1993, the size of his uniform jersey has gone from 42 to 52. His cap size has expanded from 7 1/8 to 7 1/4, even though while it was expanding he shaved his head. (Bonds reportedly shaved his head because his hair was falling out as a result of steroid use.) And Fainaru-Wada and Williams also say Murphy testified that Bonds's baseball shoe size has changed from 10½ to 13.

You can't accomplish any of this solely with healthy eating and exercise. Will notes that steriods and human growth hormone can cause the gradual enlargement of bones in the feet, hands, face, jaw and skull. Has anyone else had their shoe size grow 2 1/2 sizes starting in their 30s?

Bonds will probably overtake Hank Aaron as career home runs leader later this year, and there won't be an asterisk next to it in the record books. There's an even bigger asterisk next to Bonds name in the mind of every baseball fan.
