2009-10: Eamon McAdam played for Team Comcast U16 in suburban Philadelphia and was the top goaltender in the 2010 Liberty Bell Games. In 23 games he had a 2.47 goals against and .920 save percentage. He was selected by the London Knights in the fourth round (75th overall) of the 2010 OHL Priority Draft.
2010-11: McAdam made his USHL debut, appearing in four games for the Waterloo Black Hawks, and played nine games for the Austin Bruins in the NAHL. He was 2-2 with Waterloo and had a 3.48 goals against and .888 save percentage. One of five goalies to see action for the Bruins behind starter Keegan Asmundson, McAdam was 2-4-2 with a 3.32 goals against and .904 save percentage. He committed to playing college hockey at Penn State in 2013-14.
2011-12: Part of a crowded goaltending picture for Waterloo in his first USHL season, McAdam appeared in a team-high 23 games during the regular season. He finished the year 11-7 and had a 3.50 goals against and .882 save percentage. Waterloo finished third in the West Division and reached the playoff finals against Green Bay. Nineteen-year-old Stephon Williams started all 15 playoff games for Waterloo.
2012-13: McAdam returned to Waterloo for his second full season, splitting the goaltending duties with fellow 2013 NHL Draft prospect Cal Petersen. In 31 games he was 17-9-3 with two shutouts and had a 3.45 goals against and .896 save percentage. He appeared in two games in the playoff series with Fargo, making one start, and was 0-1 with a 3.22 goals against and .922 save percentage. The Black Hawks represented the USHL in the pre-season 2013 World Junior Club Cup in Omsk, reaching the semifinals, and in four games McAdam was 3-1 with a 2.17 goals against and .915 save percentage. He represented the USA in the 2012 World Junior A Challenge and was 4-0 with a 2.18 goals against and .927 save percentage for the gold medal-winning squad. McAdam was ranked sixth amongst North American goaltenders in Central Scouting’s final rankings prior to the 2013 NHL Draft.
2013-14: McAdam played in 10 games as a backup to sophomore Matt Skoff in his freshman season at Penn State. He was 0-9 with a 4.09 goals against and .882 save percentage. Penn State, playing in its second season of varsity hockey, finished last in the six-team Big Ten Hockey Conference in the league’s first season. The Nittany Lions defeated Michigan 2-1 in double overtime in a conference quarterfinal game before falling to Wisconsin, 2-1, in the Big Ten semifinals.
2014-15: McAdam appeared in 12 games for Penn State as a sophomore as the Nittany Lions rotated three goaltenders. He was 5-4-1 with a 3.13 goals against and .910 save percentage. Penn State finished fourth in the Big 10 but did not receive an NCAA tournament bid after falling to fifth-place Ohio State, 3-1, in the Big 10 tournament quarterfinals.
McAdam was a bit overwhelmed in his first season of college hockey at Penn State but made progress in his sophomore year. He positions himself well in the crease and is good at making saves in traffic. His talent level and athleticism suggest he can be an elite netminder but his performance has not yet matched that potential.
