Rugby has rules against both high tackles and downfield blocking. Violators are sent to what the Brits call the "sin bin" for one or two minutes, which discourages some of the more violent play we see. On the other hand, one version of rugby (Union I believe) seems an interminable slog with one teams possessing the ball forever.

I always had a fear of neck injuries for my players and my son with regards to football. Head up was the mantra, I just didn’t want that on my watch or to happen to any players or my son.

He switched to rugby and played at a high level in high school and now plays in college...I’ve never worried about him having a neck injury...ever. A broken nose worry? Yes. Maybe some wear and tear on shoulders...yes. But no serious neck injury at all

This may sound funny, but I advocate taking off the face mask as I think that protection makes Safeties and LB’s turn into guided missiles trying to lay on kill shots to WR’s and RB’s

rugby, as a contact sport, had more bruises, the occasional black eye, nose bleeds, etc.

football, as a collision sport, seems to have more joint injuries (knees, shoulders, etc.), and these days, more concussions causing missed games.
