Kanzig is a big body that can make a big presence on the ice. He has the ability to become a shutdown force for the Flames on the back end, while being an enforcer at the same time. Despite his huge size, Kanzig is a surprisingly good skater though it is an area where improvement can increase his effectiveness on the ice. He has worked to increase his technical and tactical proficiency during his junior career.
Kanzig attended training camp with Calgary before returning to Victoria for his fourth WHL season. After beginning the 2014-15 season with the Royals he was acquired by the Calgary Hitmen as part of a deal for Edmonton Oilers forward prospect Greg Chase at the WHL trade deadline. Kanzig continues to be one of the league's heavyweights while approaching career highs in goals and assists with the Hitmen. Long-term, his calling card at the NHL level will be his physical game and ability to shutdown opposition attackers; providing a complimentary element to some of the talented young forwards in Calgary.
