He graduated from Boston College High School before going to Boston College, where he was a member of the 1965 NCAA runnerup squad.
Ferris State Bulldogs
Coach: Bob Daniels, 20th season
Location: Big Rapids, Mich.
Frozen Four history: This is the first appearance for the Bulldogs, who began Division I play in 1979-80. They have one other tournament appearance. In 2002-03, they won one game. So in a two-day span, they tripled their total.
Coach: Don Lucia, 12th season
Frozen Four history: This is the Gophers' 20th appearance and fourth under Lucia. Their most recent came in 2004-05. Prior to that, Minnesota won national championships in 2001-02 and 2002-03. Overall, Minnesota has won five national titles.
Coach: Rick Bennett, first season
Location: Schenectady, N.Y.
Frozen Four history: This is the Dutchmen's first appearance. In fact, before last season, Union, which moved up from Division III in 1991-92, had never been in the Division I tournament. In 2010-11, it lost in the first round to Minnesota-Duluth, the eventual national champ. Union was the Division III runnerup in 1983-84 and lost in the national semifinals before winning the third-place game in 1984-85.
