Marion Jones, Fallen Track Star

I can't believe there was a time when I actually believed Marion Jones. Heck, my wife and I didn't miss any of her races, and we cheered for her when she won her medals.

For years, Marion Jones angrily denied using steroids. On Friday, she admitted it was all a lie.

The three-time Olympic gold medalist pleaded guilty to lying to federal investigators when she denied using performance-enhancing drugs, and announced her retirement after the hearing. Jones also pleaded guilty to a second count of lying to investigators about her association with a check-fraud scheme.

Outside the courthouse, Jones broke down in tears as she apologized for her actions, saying she fully understands she has disappointed her friends, family and supporters.

"I have let them down. I have let my country down, and I have let myself down," she said. "It is with a great amount of shame that I stand before you and tell you I have betrayed your trust.

What a waste.
