2012-13: Reilly played 37 games as a freshman at the University of Minnesota and skated for the gold medal-winning USA squad at the 2013 World Junior Championship. He scored 3 goals with 11 assists and was +1 with 14 penalty minutes as the Gophers finished first in the WCHA for the second straight year. Minnesota ended the season with back-to-back losses. Colorado College defeated the Gophers in the WCHA semifinals and Minnesota lost 3-2 to eventual national champion Yale in the NCAA West regional semifinals. Reilly's twin brothers Connor and Ryan, who are a year older than Mike, were also freshmen with the Gophers (Ryan played in in eight games while Connor has yet to play in a game). Mike Reilly scored 1 goal with 2 assists and was +4 with 4 penalty minutes for the USA at the WJC in Ufa, Russia.
Reilly is a great puck moving defenseman with good vision and a strong shot. His biggest improvements need to be on the defensive side of the game, starting with his positioning but that should come with maturity.
Alongside his brothers, Connor and Ryan, Reilly will return to the University of Minnesota to build on his impressive freshman season.
