Holzer has good size at 6’3, and continues to add strength to his frame. He initiates contact at the proper time and handles himself well in physical contests. He is calm with the puck and has a solid transition game out of the defensive zone. As the 2010-11 season wore on, Holzer started to adjust well to the speed of the smaller-ice surface. Defensively, Holzer plays sound positionally and can neutralize opposing forwards in a shut-down role.
Holzer was dealt by the Toronto Maple Leafs to the Anaheim Ducks in exchange for Eric Brewer and a draft pick.
