Seattle Seahawks quarterback Russell Wilson got emotional Thursday while remembering Trevor Moawad, a member of his inner circle who died this week from cancer at age 48.

Moawad was Wilson's longtime mental-conditioning coach, business partner and, in the quarterback's words, his best friend.

Asked about Moawad during his weekly press conference, Wilson paused, cleared his throat and prefaced his answer by telling reporters that the subject may be tough for him to talk about.

"When I think about my relationship with Trevor, I think about a man who was humble, I think about a man who always served, who always gave back, who was always dedicated to working and helping everyone," Wilson said. "And everybody he helped, it seemed that they always got better."

Wilson spoke for eight minutes straight about Moawad, first recalling when they met in 2012. Wilson was training ahead of the NFL Draft at IMG Academy, where Moawad was the director of performance, a role that included mental-conditioning work with prospective NFL players. He told Wilson then that the quarterback's mind was going separate him. They began working together regularly after Wilson's pro day.
