Injury risk is an odd one too me. I never realized 170-pound men were more susceptible to concussions or torn knee ligaments than 200-pound men.
Has there been research done backing this up? It seems pretty hard to tie an injury to someone's size.
Garland, Gaudreau, Girard, Tatar, Panarin, Gourde, Bratt, Hichier, Hughes — all 175 pounds, all seemingly surviving just fine. Slavkovsky, Samuelsson, Greenway, Muzzin, Foligno, Gudbranson, Edmunson — all 220+, all slowed by injuries.
Risk of getting knocked of the puck more easily, game not translating due to strength and speed, sure. Getting hurt, call me skeptical
