So what are the rules on hits? Looks like if one is face on, anything goes.
No entirely sure about Rugby League, but I think they are not suppose to hit above the neck for obvious safety reasons..
And you can only tackle the man with the ball, so no blocking like in American football..
Correct, AFAIW. No blocking, no stoppage of play (save for line-outs, restarts after scores, and for injuries so severe the player cannot leave the pitch unescorted), and no targeting above the neck (though, "incidental" contact is often overlooked).
