Dneen became coach of the AHL's Adirondack Red Wings in 1983 and led them to the Calder Cup in 1986 and 1989. He returned to the NHL when the Flyers hired him as their coach on Dec. 4, 1991. He was fired on May 24, 1993, after Philadelphia went 60-60-20.
Three of his sons, Kevin, Gord and Peter, played in the NHL. Kevin, who played for his father with Philadelphia from 1991-93, scored 355 goals in 1,188 regular-season games.
"Wonderful hockey family," said Flyers president Paul Holmgren, who was replaced by Dineen as coach in 1991. "His boys are scattered all over the map, and they're all good guys just like Billy. Just a tremendous hockey family.
