Among things ruining the game are acts of foul play such as O'Donoghue and Jean Deysel produced in a weekend that equalled the list for crimes in any round of this year's Super 15. Eight players were sinbinned and Deysel (stomping) and O'Donoghue (gouging) sent off.
Players tolerate high levels of panelbeating in the modern game, they accept they will be bashed, hammered and attacked all over the park but never around the head or the family jewels. Those areas are sacrosanct.
There was a mature response from Sharks coach Jake White when he commented, adversely, on Deysel lashing out when his foot was held by Crusaders flanker Jordan Taufua.
White's view may have been different had the Sharks not grabbed an extraordinary victory, but it's unlikely.
Contrast that with Horwill's irrational eruption and the mute attendance of his coach Richard Graham.
Was that the silence of a coach who agreed, held the opposite opinion or decided to stay quiet to avoid any fine?
None of that was discovered by the media at Suncorp Stadium - their inquiries seemed to replicate the submissive television commentators.
There were incensed noises from some areas that the foul play incidents were discovered only because of a break in play and the insistence of a TMO and that the increased use of technology would mean a dissection of every piece of footage.
If it means acts of violence are seen and acted on, great, and if stupid acts like Ash Dixon are caught and cost the Hurricanes a win against the Highlanders, all power to the replays and the TMO.
At some stage the message will get through to players and coaches.
