Violence in sport

Violence in sport
I am sure everyone who watched State of Origin on Wednesday night has an opinion on the sending off  of four players after a punch was thrown. The general feedback from the media (ex footy players mainly) is the new rule of sin binning a player for throwing a punch is making  the game a game for sissy's! One retired legend of the game said he believed the game could be played without the thuggery and still be played hard and be a great spectacle.
I don't know how many saw the 60minutes story on the link between dementia and head trauma but it was conclusive in its findings
 taken across a wide section of football players(current and retired) that the two were linked.
The banning of the king hit or punching will not stop all head trauma as whiplash will occur in tackling and hitting the ground but every little bit helps.
As a grandmother with children playing contact sports I am happy to see any improvement in the safety aspect of sport ,it has been reported that the incidents of violence in junior club football always escalates after a high profile match .
Maybe I am mistaken in believing the young players watch their hero's very closely and try to emulate their behavior.From what I see the is nothing sissy about playing any footy even without the violence!
Just my opinion!
