"Whether it was behind the scenes or under the glare of hockey's harshest spotlight, Brendan was as much of an 'impact player' at the League as he was on the ice. Brendan brought commitment, clarity and impeccable credibility to his difficult and thankless duties here, and while we are sad to see him go, we knew his unique skill-set and body of work in the sport would make him a valued leader for any Club. Brendan has helped to change the culture of the game, has made it safer on a variety of levels, and his influence will be felt for years. We send him to his new role with our best wishes and our deep appreciation for his many contributions to the game."
