Rugby may well be a contact sport, but I've had a quick look and thumping people isn't in the rules.
OK, everyone agrees it was unacceptable, what remains is how it is dealt with.
A disciplinary hearing isn't going to impose much of a sanction, sports ones never do. Does that matter? Yes, it does simply because it sends the wrong message to others, not just in rugby, but in wider society.
The problem is that UK wide we have a problem with people who think that OTT violence is acceptable, why? Because time and time again they see it happen and very often they see no consequences for that violence.
Like it or not Flowers put himself in the public eye when he signed on the dotted line, and in doing so he should be expected to set an example, part of that is facing up to the consequences of his actions.
A Dsciplinary board is not the answer here, it's a Court hearing that needs to happen. Excuses being made for him are not helping anyone, the contact sport argument is cobblers, contact means just that, it does not mean a thump in the face on another player who does not have the ball, who is on his back, and possibly unconscious.
