There are many great moments in sports, but very few of them happened more than once. Wilt never scored another 100 points, no one hits 70+ HR a year for several years, very few teams dominate a decade with championships, there are too many variables that have to be controlled for them to happen.

This is why I think that Lance Armstrong has accomplished the greatest feat(s) in sports. He was a dominate rider( youngest world champion, TDF stage winner,) before over coming terminal cancer to win the TDF (tour de france) SEVEN times in a row. The TDF is the most physical, emotional, and mental challenge in sports. Cycling has so many variables to it, its nearly impossible to control them.

In addition how many of our sports "icons" raise the awareness level of a cause (Cancer) to the level he has, how many drop millions into the cause? Answer: Not a enough....Period.

Lance Armstrong has accomplished the greatest feat(s) in sports, he has raised the bar for all that follow; to become a social icon for a cause and the most dominate sportsman in 10 year period. No one else holds a candle to this!!
