A couple things. As it stands you can not sign away your rights to a safe workplace. No waiver can possibly be ironclad and making one would actually open the NRL up to lawsuits as they are admitting the workplace is not safe.Iv no doubt your spot on, someone I saw made a great point I think on 360 funny enough, can't remember which journo, to paraphrase they said the issues and legal issues the N.F.L had to deal with won't affect the N.R.L, they were saying that the N.F.L had the data about CTE and other brain trauma and kept it locked away, where the N.R.L were totally open and transparent with the whole thing. Someone on the forum also made a great point that the players are consenting adults and know the risks. If a player is willing to put their safety on the line to play a sport, mind you that they are mostly well paid to perform, then who is any doctor, lawyer or N.R.L governing body to say no. As long as their of sound mind, they're adults. They said and I totally agree, all juniors by their parents and part of every registered N.R.L contract as an adult should have a stipulation they understand the risks, have a list of issues head trauma, other injuries that may or may not be lifelong, that they know and understand the risks and by signing the contract will not hold the N.R.L liable for any injury or life long illness incurred through their time playing, whilst uncontracted at a club or in retirement. Make it iron clad, it's the only way to fix it. The N.R.L are petrified of the lawyers so they've brought in doctors to help to protect them in a way legally, but the doctors know medicine with no concept of playing an extremely fast sport with massive bodies having huge collisions. By bringing in doctors they're objective is to protect the players, left alone the doctors will just turn it in to Oz tag to meet they're objective because they're objective has no context within the game. I just think that all players from juniors right through should be made to sign iron clad legal documents that accept the risk and won't hold the game or clubs responsible obviously unless of gross negligence, if the players are too young the parents can. Then we can finally bugger the doctors and lawyers off and the game can just be the game again.
The comparison to NFL is valid however and the knowing the risks argument exists however it would really come down to how well argued the point was on both sides. As the game is a workplace, the accepting the risks argument is different to say boxing where the boxers are essentially self employed contractors.
The phrasing of the situation by the likes of Abdo is very deliberate saying it's not a crackdown we have been penalising/sin binning high shots for decades is made to refer back to anyone considering the legal avenue now that "the NRL is only just now getting serious about CTE, it wasn't when I played".
