Rau'shee Warren, men's boxing
Warren will be making an unprecedented return to box at the Olympics for a third time -- thanks to a promise he made to his mom. The youngest of four brothers (two of whom have been in prison since Warren was a teenager), he grew up in the roughest housing project in Cincinnati. That he got out is impressive on its own. But Warren went a step further, swearing to Mom that he wouldn't turn pro after Beijing (a move that would have been expected) so that he could bring her a gold medal. Let's hope he makes Ma proud.
