"I know you loved your husband, and boys you loved your dad… And he knew it," an emotional Mason said to McNair's wife and sons.
Mason was one of several former teammates and coaches who spoke at McNair's memorial service in Nashville. Authorities say McNair, 36, was fatally shot by his mistress, Sahel Kazemi, 20, who then turned the gun on herself in a murder-suicide.
Thousands of fans attended the gathering to remember the slain ex-NFL quarterback's accomplishments on and off the field. Mason, who played with McNair in both Tennessee and Baltimore, called the loss heartbreaking.
Tennessee Titans coach Jeff Fisher and former Titans running back Eddie George also spoke at the service.
George, who played with McNair on the Titans team that reached Super Bowl XXXIV, spoke of his respect for McNair's playing ability.
When asked by a friend if he thought McNair would be in the Hall of Fame, George responded, "I had to chuckle, he's already in the hall of fame."
