2010-11: Thatcher Demko played midget hockey for the Tier 1 Junior Gulls program in southern Callfornia. In 25 games he was 12-12-1 with a 2.47 goals against and .913 save percentage. Demko was invited to USA Hockey’s Select 16 Player Development camp in Rochester, NY in June 2011 and was selected to represent the USA in the 2011 U17 Five Nations Cup in August 2011.
2011-12: Demko returned to California after winning a gold medal with the USA U17 squad at the 2011 Five Nations Tournament in August. He spent just over a month with the U16 Los Angeles Junior Kings before joining the USHL’s Omaha Lancers in December. Demko represented the USA at the 2012 U17 World Hockey Challenge in Canada. In 15 games with the Lancers he was 9-3 with 1 shutout and had a 2.87 goals against and .899 save percentage. Demko played seven games with the Junior Kings; posting a 2.29 goals against and .907 save percentage. He appeared in two games at the WHC and had a 1.09 goals against and .949 save percentage, recording 22 saves in a shootout victory over Sweden in the semifinals, and was 2-0 in three games at the Five Nations Tournament with a 2.63 goals against and .911 save percentage.
2012-13: Demko was invited to join USA Hockey’s National Team Development Program in Ann Arbor, MI — skating for the NDTP’s U18 squad as a 16-year-old — and in December 2012 committed to playing college hockey at Boston College in 2013-14. He played for Team USA’s U18 team in the 2012 Ivan Hlinka Memorial Tournament and at the 2013 World Junior Championship in Sochi, Russia. He was 31-9-3 with six shutouts and had a 2.06 goals against and .911 save percentage in 45 games for the NDTP’s U18 team. Demko was 2-2 in four games at the Ivan Hlinka Tournament, with both losses coming in overtime, and had a 3.27 goals against and .895 save percentage. He was 4-3 in seven games with one shutout for the USA silver medal-winning squad in Sochi; posting a 2.24 goals against and .899 save percentage.
2013-14: Thatcher Demko gradually assumed the starting position for Boston College as a freshman after splitting time with junior Brian Billett early in the year; backstopping the Eagles to the Frozen Four semifinals. In 24 games he was 16-5-3 with two shutouts and had a 2.24 goals against and .919 save percentage. BC won the Hockey East regular season title and was among the top-ranked teams in the country most of the year. The Eagles were upset by Notre Dame in a three-game Hockey East quarterfinal series but rebounded to capture the NCAA Northeast Regional — defeating Denver and Massachusetts-Lowell — before falling 5-4 to eventual national champion Union, 5-4, in a Frozen Four semifinal game. Demko was one of three goalies invited to USA Hockey’s U20 evaluation camp in July and was with the team at the 2014 World Junior Championship but did not see any action. He played for Team Johnson in the 2013 USA Hockey/CCM All-American Prospects game in September. Demko was the top ranked North American goaltender in the Central Scouting final rankings and was selected by Vancouver in the second round (36th overall) in the 2014 NHL Draft.
Demko is a goalie that plays with a calm and maturity that is rare for a goalie of his age — making his NCAA debut as a 17-year-old. He relies on technique and positioning, using his large frame and good lateral mobility to make it a challenge for shooters to find holes. He plays an efficient game with little wasted movement.
Demko is in his sophomore season at Boston College in 2014-15 and played for the USA at the 2015 World Junior Championship. The Eagles have once again been one of the top teams in college hockey and Demko has been a big part of their success — appearing in 31 of 34 regular season games. Projecting future success for goalies, especially goalies who are still in their teens, is an inexact science but long-term Demko is viewed as an eventual NHL starter with the potential to be a top netminder one day.
