in my opinion may should have never got charged for standing his ground,some responsibilty must go to the other player to be aware of whats around him, he clearly wasnt watching what he was about to run into.In my playing days you knew you were going to be belted so you stayed aware and protected yourself or took avasive action.I cant remember too many concussions back in the hard days of afl/vfl the players played hard but fair tough footy,with occasional exception,like Mathews whak on bruns,the players knew to be aware of what could happen on the ground[what happens on the ground stays on the ground]would love to hear jeff crouch opinion of todays players.he umpired some of toughest players of all time
