If there is such a thing as a hockey gene, Bob Johnson surely had it.

Twenty-five years after his death, Johnson’s influence extends from the N.H.L., where he helped pave the way for American college players and coaches in a league then dominated by Canadians, to N.C.A.A. hockey, which he endlessly promoted.

Johnson died of brain cancer at age 60 on Nov. 26, 1991, six months after leading the Pittsburgh Penguins to their first Stanley Cup in his only year as coach.

Yet his signature saying, “It’s a great day for hockey,” is still painted above the stick rack outside the team’s locker room at PPG Paints Arena, which opened in 2010. It also hangs from a banner at Honnen Ice Arena at Colorado College, where Johnson started his coaching career in 1963.
