SI.com writer Peter McEntegart repeats a slightly different variation of a stat I saw Peter Gammons citing the other day:
The most astounding number to come out of the Barry Bonds steroid controversy is not that 93 percent of the 40,000-plus voters on a SI.com poll don’t believe Bonds’ claim that he was unaware he took steroids. The more intriguing number comes from Stats Inc., which reports that Bonds had never hit a home run longer than 450 feet before the 2000 season, when he turned 36. Since then, he’s hit at least 21 homers of 450 feet or farther.
WFAN’s Christopher Russo interviewed a home run distance expert who claimed that prior to 2000, Bonds hit three homers longer than 450 feet; in the last five years, he has hit 26.
Either way�well�it seems like telling circumstantial evidence.
