2009-10: The second overall selection in the 2009 WHL Bantam Draft (by Moose Jaw), Morgan Rielly skated for the midget AAA Notre Dame Hounds in Saskatchewan. In 43 games he scored 18 goals with 37 assists and had 20 penalty minutes. Rielly scored 7 goals with 2 assists in 13 playoff games for the Hounds.
2010-11: Rielly joined the Moose Jaw Warriors for his first WHL season and was selected to play for Canada at the 2011 U18 World Junior Championship as a 16-year-old. He also skated for Canada Pacific at the U17 World Hockey Challenge. In 65 games for the East Division champion Warriors he scored 6 goals with 22 assists and was minus-15 with 21 penalty minutes. Rielly skated in six playoff games for the Warriors and was minus-3 with 6 assists. He skated in all seven games for Canada at the U18 WJC and scored 2 goals with 1 assist and was minus-3. Canada lost to Russia in the bronze medal game. In six games for Canada Pacific at the World Hockey Challenge he scored 2 goals with 3 assists and 4 penalty minutes.
2011-12: Rielly got off to a fast start for Moose Jaw and appeared to be headed for a big year before suffering a knee injury in the early fall that would keep him out for the rest of the regular season. He scored 3 goals with 15 assists and was plus-6 in 18 games before being injured. Rielly returned for the Warriors' first round playoff series with Regina; skating in all five games and posting 3 assists while finishing minus-1. Rielly was ranked fifth amongst North American Skaters in Central Scouting's final rankings prior to the 2012 NHL Draft.
Rielly was the top offensive defenseman in the 2012 draft class. His skating, passing, and puck skills are all top-notch, and he puts those skills to good use. Rielly has the look of a future power-play quarterback and puck-rushing defenseman. He'll need to work on his defensive game, but that isn't likely to keep him from making an arrival in the NHL sooner rather than later.
Rielly has returned to the WHL for the 2012-13 season to play for the Moose Jaw Warriors.
