What was a split second of stupidity on the part of the tacklers has had an earth-shattering outcome and drastically altered the course of this young man's life. McKinnon's league career is over and he is facing a battle exponentially greater than what he ever experienced on the field.
The shocking incident will also no doubt drastically alter how the NRL deals with dangerous play on the field in the future, with league bosses under pressure to impose tougher sanctions on players involved in reckless acts. Now we have been reminded of the devastating consequences of these tackling techniques - for both the tacklers as well as those on the receiving end - the NRL need to carefully consider their next move.
There have been a number of suggestions over what tough new measures the NRL should impose on players found guilty of lifting in tackles, from automatic red cards, lengthy suspensions and massive fines on the individual. These are all worth investigating.
Whatever the NRL can do to deter dangerous play is ultimately a good thing, but it won't do the sport any good to make an example out of the players involved in the McKinnon tackle.
Storm front rower Jordan McLean will face the judiciary tonight over his role in the tackle. Regardless of what McLean's career holds, he will be forever linked to this incident.
The NRL have a duty of care in his case as well.
