Reactions to the death of Jim Brown, former NFL star, actor and activist:

“To the world, he was an activist, actor, and football star. To our family, he was a loving husband, father, and grandfather. Our hearts are broken.” - Brown’s wife, Monique Brown, on Instagram.

“Jim Brown is a true icon of not just the Cleveland Browns but the entire NFL. He was certainly the greatest to ever put on a Browns uniform and arguably one of the greatest players in NFL history. Jim was one of the reasons the Browns have such a tremendous fan base today. So many people grew up watching him just dominate every time he stepped onto the football field but his countless accolades on the field only tell a small part of his story. His commitment to making a positive impact for all of humanity off the field is what he should also be known for.” - Browns owners Dee and Jimmy Haslam.

“Jim Brown was a gifted athlete - one of the most dominant players to ever step on any athletic field - but also a cultural figure who helped promote change. During his nine-year NFL career, which coincided with the civil rights movement here at home, he became a forerunner and role model for athletes being involved in social initiatives outside their sport.” - NFL commissioner Roger Goodell.

“I’ve said many times, and I will always say, Jim Brown is the best, and he will still be the best long after all his records are broken.” - Hall of Fame running back Gale Sayers.
