LeBron James vowed Friday that he and his Los Angeles Lakers teammates would continue the legacy of club icon Kobe Bryant, who died Sunday in a helicopter crash. James, his voice fraught with emotion, addressed the Staples Center crowd before the Lakers returned to NBA action for the first time since Bryant's death. Flinging away his prepared notes, James said to cheers he would speak from the heart, calling on all present to celebrate Bryant's life and a career that included five NBA titles in 20 years with the Lakers.
