2008-09: Justin Holl skated in 28 games for Minnesota's Minnetonka HS as a junior. He finished the season with 1 goal, 9 assists and 6 PMs. The Skippers were one of the top ranked teams in the state and faced Edina in the Section 6AA final.
2009-10: Played for Minnetonka High School, and then finished the season with the USHL's Omaha Lancers. In 31 games for Minnetonka, Holl scored 20 goals and added 17 assists. In his 11-game stint with the Lancers, Holl picked up 4 assists and had a +7 rating. In 8 playoff games for the Lancers, Holl scored 1 goal and added 1 assist.
2010-11: Holl was in and out of the lineup at the University of Minnesota as a freshman, appearing in 25 games with 1 goal, 6 assists for 7 points. He was limited to a checking role for much of the season on the Gopher's veteran blue line.
2011-12: Holl, a sophomore, was one of four Minnesota underclassmen on defense to play in every game as the Gophers enjoyed their winningest season since 2006-07. In 43 games he scored 3 goals with 8 assists and was plus-18 with 34 penalty minutes. The Gophers won the WCHA regular season title and reached the NCAA Frozen Four. Minnesota defeated North Dakota in the NCAA West regional final after having lost to the Fighting Sioux in the WCHA tournament semifinals.
Holl combines a projectable 6'2 frame with excellent skating ability. He is a strong puck-mover on the blue line with great vision and passing ability. His defensive-zone play has improved over the course of his first two college seasons as he has logged significant minutes in a checking role. Although he is still filling out and not overly-physical, he instead relies on positioning and quick reads to make plays in his own zone.
Entering his junior season at the University of Minnesota, Holl should continue to see plenty of ice time in defensive situations. He may be capable of more offensive production if given the opportunity, but the Gophers will return their entire defensive corps in 2012-13.
