Mike was a two-sport standout for the Riders in both football and hockey. In football, he was a significant contributor as a defensive end, tight end, and kicker for the Roughriders and helped lead them to a 7-3 record and state playoff appearance in 1984.  On the ice, LaMoine was a four-year varsity regular, earning All-EDC and All-State honors in 1985. He was a captain for the 1984 and 1985 teams and helped the Riders win EDC team titles in 1983 and 1985. LaMoine played four years at the University of North Dakota, winning a National Championship with the Fighting Sioux in 1987. In that same year, he was drafted by the Detroit Red Wings and participated in the Olympic Festival on the gold medal-winning team. After his playing days were over, LaMoine gave back to RRHS, serving as an assistant hockey coach from 1990-1996 and interim head coach in 2020. During his single season as head coach for the Riders, he was named the ND Boys Coach of the Year and led them to a State Championship.
