2012-13: Dillon played for the Westshore Wolves junior B team in the Vancouver Island Junior Hockey League as a 16-year-old. He posted a 3.96 goals against and .890 save percentage in 24 regular season games and had a 3.90 goals against and .892 save percentage in three playoff games.
2013-14: Dillon committed to playing college hockey at RPI in 2015-16 in September and skated for the Victoria Grizzlies in the British Columbia Hockey League, splitting time with the 19-year-old Reynard. He was 21-7-2 with 1 shutout in 33 games and had a 2.76 goals against and .910 save percentage. Victoria finished first in the Island Division and reached the playoff semifinals. Dillon played in nine playoff games and was 4-4 with 2 shutouts; posting a 2.56 goals against and .908 save percentage. Dillon was ranked 13th amongst North American goalies in the Central Scouting final rankings and was selected by Los Angeles in the fifth round (150th overall) of the 2014 NHL Draft.
2014-15: Dillon played for the Tri-City Storm in the USHL. In 41 games he was 23-11-4 with three shutouts and had a 2.27 goals against and .914 save percentage. The Storm finished second in the Western Conference and reached the conference finals against Clark Cup champion Sioux Falls. Dillon was 4-2 in six playoff games with a 2.17 goals against and .923 save percentage. In May 2015 he signed with the WHL’s Edmonton Oil Kings for 2015-16.
2015-16: Dillon played seven games for the WHL’s Edmonton Oil Kings, suffering a season-ending lower-body injury at the end of October. He was 2-2-1 with a 3.81 goals against and .871 save percentage.
Dillon was a long-term project when he was selected in the 2014 NHL Draft — picked as much for his size and projectable frame as for his play to-date. He is a massive goaltender with long arms and legs. Dillon covers the net extremely well, and when he plays his positioning correctly, he is a challenging figure to beat. He is a very raw talent, but with that sort of physical make up, he is an intriguing goaltender to develop. He will likely need to increase his agility and work on his strength and technique to eventually compete at the NHL level.
Dillon missed most of the 2015-16 season after suffering a lower-body injury in October 2015. A raw goaltending prospect with ideal size and athleticism, he is still a long range project at this point. He will likely spend an overage season in major junior as a 20-year-old in 2016-17 but his future is uncertain at this point.
