Before they were honored at the Grizzlies-Pelicans game, four former sports stars discussed Martin Luther King's impact on their lives, the work they're doing to help carry on his legacy and their responsibilities to the community Monday at the Earl Lloyd Sports Legacy Symposium.

Doug Williams, Robert Parish, Sheryl Swoopes and Caron Butler were this year's Sports Legacy Award honorees.

The event, which is named for the first black player to play in the NBA, is part of the Grizzlies' week-long celebration of King's life and accomplishments. 

"To stand behind what you represent firmly and be willing to sacrifice your life with your family in danger, being a leader of individuals," said Butler, who is a two-time NBA All-Star. "And to have that foresight of 'I've been to the mountaintop and I've seen the promised land' and trust in the vision, that speaks volumes. He was one of a kind."
