Baltimore Ravens linebacker Ray Lewis is going to retire at some point, even though it seems like the 37-year-old will play forever. When Lewis calls it quits, my guess is he'll always have a place in locker rooms across the country.

Over the past year, Lewis has been motivating players with inspirational speeches. And he's putting an impressive resume along the way. After hearing Lewis talk, the Stanford men's basketball team and the Loyola men's lacrosse team each won championships.
