Defenseman Jim Boo played three years of collegiate hockey with the University of Minnesota, a school that annually ranks among the best in the NCAA. During his final year in 1977-78 he recorded 21 points in 37 games. Several of Boo's teammates such as Steve Christoff, Phil Verchota, Rob McClanahan and Bill Baker later went on to win the Miracle On Ice gold medal at the 1980 Olympics for the United States.
In March, 1978 the Minnesota North Stars were hard hit by nagging injuries to some of their regular roster players so they offered Boo a free-agent contract, which he gladly accepted. It was the highlight of his career not only to play in the NHL, but in front of his home fans in Minnesota. Although it lasted just six games, Boo played with enthusiasm and toughness and was not shy about being aggressive, collecting 22 minutes in penalties.
Boo played a couple of seasons in the Central Hockey League with the Oklahoma Stars, retiring after the 1979-80 campaign. Although his on-ice credentials will never land him in the Hall of Fame, he can be found listed on the Hall's website humour section, honoured for being named to the forward line on the tongue-in-cheek "Scarey Line 1" along with Adam Graves and Butch Deadmarsh..
