Martin Hanzal is a big dude. He’s listed as 6’ 6” (without skates, which add an inch or two to every player) and 230 pounds. He’s a solid guy, and his long reach is often a benefit to his ability to play a two-way game.
Unfortunately, because of his size relative to other guys on the ice, it can also mean he goes in for a hit and ends up making primary contact with a guy’s head when he’s aiming for shoulders. The thing is, recent years have more than reinforced the idea that hitters are responsible for where they deliver a hit.
