According to Lance Williams and Mark Fainaru-Wada, the authors of Game of Shadows, Barry Bonds went from size 10 1/2 to size 13 cleats in his years with the Giants. Moreover, they state that "medical experts said overuse of human growth hormone could cause an adult's extremities to begin growing, aping the symptoms of the glandular disorder acromegaly." I don't have much to add to that, other than the fact that we've all been making jokes about Bonds's expanding head, but we were paying attention to the wrong end of his body.
The evidence that Bonds used a variety of steroids is, at this point, absolutely overwhelming. The fact that he hasn't challenged the factual statements set forth in Game of Shadows, despite the fact that he has more than enough cash for a spirited libel claim, is telling. This would be a good summer to be hiking the Hindu Kush to escape the media's saturation coverage of Bonds's grim pursuit of 755 home runs. With no major soccer tournament in the summer, we're going to have nothing to divert our attention from Bonds. It's going to get to the point where I'll be looking forward to coverage of the Red Sox and Yankees on SportsCenter.
