[1] Mattson grew up playing junior hockey in the Minnesota area, but for his senior year of high school he headed to Nova Scotia.
The team played so well that they were able to schedule an exhibition match with the Chicago Black Hawks before heading to Colorado Springs for the NCAA Tournament.
Minnesota was preparing to win their first title when Abbie Moore fired the puck past Mattson with less than four minutes to play and regulation ended in a tie.
For the first overtime championship game, Minnesota appeared sluggish at the start and Rensselaer took full advantage, keeping Gophers hemmed in their own end and scoring on just the second shot in the extra session.
While the finish wasn't the send-off he may have wanted, Mattson ended his career at Minnesota as the program's all-time leader in wins (50, a then-NCAA record), goals against average (2.86) and save percentage (.896).
