Prior to attending St. Cloud State, Lee was the goaltender for the Fargo Force of the USHL in 2008-9.[3][4][5] Despite being an expansion team, Lee led the Force to the USHL playoff finals.[5] As a high school goaltender, Lee helped the Roseau Rams to the Minnesota state hockey championship.[6][7]
Lee was the first American goalie selected in the 2009 draft.[3] He also played on the gold-medal winning USA team at the 2010 IIHF World Juniors.[4] Lee started for Team USA in the gold medal game, but was relieved by Jack Campbell in the second period.[8][9] When the Coyotes traded away backup goalie Devan Dubnyk, Lee was called up to be Mike Smith's new backup, putting Lee in the NHL for the first time. However, he was sent down in favor of Mike McKenna before entering a game.
