Harvard linebacker Zach Kastenhuber brings old-school toughness and proven disruptive upside
Zach Kastenhuber is a physical, high-motor linebacker whose recruiting profile showed real playmaking pop, including 107 tackles, 44 tackles for loss, and 18 sacks in his dominant prep season before Harvard. His edge comes from aggression, pursuit, and contact balance — the kind of player who can change tone even when the stat sheet is quiet. For Harvard, he reads as a fit if you want toughness, special-teams value, and a linebacker who plays like every snap has a grudge attached to it.
