2008-09: Kevin Gravel played in the NAHL for the Marquette Rangers. In 58 games for the Rangers, Gravel scored 3 goals and added 11 assists for 14 points. He played for Team USA at the 2009 Ivan Hlinka Memorial Tournament.
2009-10: Gravel's rookie season in the USHL with the Sioux City Muskateers. In 53 games for the Muskateers, he scored 3 goals and added 3 assists for 6 points. He participated in the 2010 USHL All-Star Game. Fallon was injured for a bit in the early part of the season.
2010-11: Gravel skated in 36 of 38 games as a freshman at St. Cloud State and provided steady, if unspectacular, defense-first play for the Huskies. Gravel's -7 plus/minus could partly be attributed to the Huskies' team struggles; St. Cloud slid to eighth (tied) in the WCHA after reaching the NCAA tournament one season earlier. Offensively, Gravel scored 1 goal with 5 assists.
2011-12: Gravel was a fixture on the second pairing for St. Cloud State as a sophomore and played for the USA in the 2012 U20 World Junior Championship. He scored 1 goal with 7 assists and was plus-two with 12 penalty minutes in 37 games. The Huskies struggled to stay above .500 for much of the year; finishing sixth in the WCHA during the regular season and falling to eventual champion North Dakota in the WCHA Final Five quarterfinal game. Gravel played six games for the seventh-place USA at the WJC and was plus-two with 1 goal.
2012-13: Gravel played in all 42 games for St. Cloud State in his junior season. Paired with sophomore Tim Daly, he scored 1 goal with 11 assists and was +2 with 25 penalty minutes. The Huskies finished tied with Minnesota for first in the WCHA and rebounded from a loss to Wisconsin in the WCHA semifinals to reach the Frozen Four. St. Cloud State defeated Notre Dame (5-1) and Miami (4-1) to capture the NCAA Midwest Regional before falling to Quinnipiac, 4-1, in the Frozen Four semifinals.
Gravel has very good skating for his size, including a good first step. His defensive positioning is exceptional and has become a real staple and defining factor to his game. He should have more points than he does given his puck skills and shot.
Gravel is going to return to St. Cloud State for his senior year in 2013-14. He has impressed numerous people so far in his development and is widely considered the best defensive defenseman in the Kings’ system.
