Not going to argue anymore. We clearly are arguing over different things. I have stated that they need to protect against these types of injuries but to a certain extent. Otherwise; this game as we know it will be something totally different. There will always be another potentially dangerous side-effect from this sport. Maybe the NFL should just write-in clauses from now on and let the players themselves decide if they want to play or not.
An example
I am a certified DiveMaster and close to an instructor. I love diving and do it often. Awhile back, I had the opportunity to become a DeepSea welder. Now, I know that is lucrative, dangerous work but it can't be healthy. We are not made to go down hundreds of feet for extended periods of time. Not getting into blood gases, atmospheric pressure and the like, I used my common sense and decided not to take the risks of that career. It may or may not be safer than an NFL player, but I thought it was too dangerous so I passed.
There has been insufficient research done on the effects of deep diving and I knew this. If I accepted the job, then I would have held only myself accountable for future repercussions.
Well, if you've been watching football as long as I have (and maybe you have), you'll realize the game has changed and keeps changing over the years. Goalposts used to be 10 yard closer, which made field goals much easier. Too easy, so they changed the game.
There used to be a position called "fullback", and he carried the ball quite a bit out of the pro set. Pretty much extinct. That's the game changing itself, which happens -- though I'd say rule changes that promoted passing over running accelerated the process.
Players who made a TD might spike the ball. But they didn't do a little dance after every decent play. The game changes.
And your example about deep-sea welding makes my point. You are -- I presume -- in control of your equipment and the other circumstances of any dive and recognize that, even with that level of control, the inherent risks that you know about convinced you that the risk was not worth the reward. And the activity is similar to regular diving, but with special and recognizably more dangerous circumstances.
A football player who makes it to the NFL has no such control over equipment or working conditions. The risks APPEAR to be manageable, since it's very much like what he's been doing since Pee Wee League. In fact, the risks don't appear to be greater than those he is used to. And the reward appears to be enormous relative to those apparent risks. But more and very serious risks are emerging that need to be dealt with or at least recognized -- and perhaps can be minimized without great violence to the rules of the current game. That's why I'm in favor of any steps that minimize those serious risks.
