Boldon had 28 sub-ten 100m races and 9 sub-20 200m in 6 years, that's top 3 of all time. That he has only one gold medal doesn't mean too much. It was just his bad luck that Greene was there.
Boldon says on his website that the horrible car crash in Trinidad was his end in 2001. He never ran under 10 sec. again after that.
I just saw that Ato posts one story of the past each month on his website. A great service for his fans, he always had the best website compared to the others.
