Upon his arrival in the NHL, Daneyko established himself as a stay-at-home defenseman, and soon won fans over with his gritty and self-sacrificing play. Daneyko was also known for his missing front teeth, lost after he was hit in the mouth by a puck. His gap-toothed smile was well known not only by Devils supporters, but by hockey fans around the world. As a player who had spent all of his NHL career with New Jersey, Daneyko was nicknamed “Mr. Devil”.

Daneyko currently holds both the franchise record for games played as a Devil with 1,283 games and in penalty minutes with 2,516 as well as 175 playoff games.

Alongside the great Martin Brodeur, Scott Stevens and Scott Neidermeyer, he was part of a Devils defensive core that lifted the Stanley Cup three times, in 1995, 2000 and 2003.

He had the distinguished honor of having his number “3” raised to the rafters on March 24, 2006.

Currently, Daneyko remains part of the Devils organization as a team ambassador, and in 2023 celebrated his 40th year with the team.

He provides the color commentary for the Devils Broadcast on MSG Networks.

Daneyko is also very active in philanthropy in New Jersey and is a board member for the Center for Great Expectations, where he lends his name to the Ken Daneyko Golf Outing each year.

Daneyko currently lives with his wife Margaret, and is a proud father and grandfather.
