I think that's a keen observation. There are indeed ACL injuries here and there, hamstring tears, groin muscle pulls, but these are typically a result of hyperextension from flukey plays, usually involving falls and/or an impact with the boards. Not many soft tissue injuries, no. Shoulder injuries I'm sure are more common in hockey as that's how they throw and receive hits, rather than the face to face impacts like you see in gridiron.You know what? I bet there aren't as many soft tissue injuries, blown ACLs, torn Achilles, detached hamstrings, and the like playing on skates as opposed to cleats on the ground. You're kind of unanchored being on ice, right?
