I mean, it could be debatable but from my perspective it seems ever since they started enforcing penalties against high hits and helmet to helmet collisions with the fines, more and more players are hitting lower and aiming for the legs. I'm seeing guys with more leg injuries like (e.g. torn acl, lcl, hamstring issues, knee issues, broken ankels, foot injuries) all the way around, IMO. I think i would rather take a helmet to the shoulder chest area than a helmet to the knee/leg area.
