A stay-at-home defenseman, Lorenz was +7 with 3 assists and 18 PMs. The Fighting Irish won the CCHA regular season and playoff titles but were shocked by Bemidji State in their first NCAA tournament game, finishing the season 31-6-3.
2009-10: Lorenz played 34 of 38 games for Notre Dame as a sophomore – missing four games due to a leg injury. He scored his first two college goals and had one assist and was -9 with 14 PMs. Notre Dame slipped to ninth in the CCHA one year after winning the league.
2010-11: Lorenz skated in all 44 games for Notre Dame as a junior and was named the CCHA's top defensive defenseman; leading all CCHA skaters with a +33 plus/minus. Offensively he scored 4 goals with 11 assists (both career highs). Team-wise, the Irish returned to the upper echelons of college hockey, finishing second in the CCHA behind Michigan and playing in the Frozen Four after winning the NCAA Northeast Regional title.
Lorenz is a tough, stay-at-home defenseman. He skates well, has good size. Needs to work on puckhandling and better zone coverage.
Finishing his senior year at the University of Notre Dame, and could provide an excellent option for Houston next season.
