The real issue with brain injury and football is the g forces the head takes, the human brain is not anchored, it moves around in the head, and when you are playing football when you get hit, there is massive deceleration, a typical hit is 30-50gs, and some can go as high as 150gs. Better helmets help to a certain extent (the foam getting crushed when you decelerate helps cut down the g forces some), but no helmet can bring a 100g hit down to ‘normal’ range.
Measuring the number of concussions means very little to nothing, because as others rightfully point out, the concussion is a conclusion of a certain number of hits, but players routinely take hard hits that are way, way up there, and don’t get concussions from it, and the point of CTE is that apparently it is caused by the brain repeatedly being banged around, it accumulates, so one bad hit that causes a concussion might cause X amount of damage with that one hit, but you might get that same amount of X damage from let’s say 10 repeated hits that are large but don’t cause a concussion. In a sense the concussion issue is kind of a red herring and might be a dangerous one IMO, because the NFL can say “we have reduced the number of concussions from 150 a season to 50, and players now have to wait until they are recovered to play again”, but that of course doesn’t address the routine, non concussive hits. Popular perception and the NFL now encourages this, is that only concussion level hits cause problems, but the reality is normal physics does, but by focusing on Concussions the NFL can create a smokescreen about how they have fixed the ‘concussion’ problem. Personally I trust the NFL about as much as I trust politicians promises, this is the same NFL that had as head of their so called ‘concussion’ panel a doctor (and I use that term loosely) who was a rheumatologist who got his medical degree from some medical school in Guadalajara and who was telling neurologists and neuropathologists who were experts and had gone to top notch research medical schools they didn’t know what they are talking about.
I agree that the number in this study is meaningless, in the sense that it is a self directed study, ie the people involved likely had symptoms and their family wanted them checked. In a perfect world, the families of former players would agree routinely to any player who has died, or anyone who played football, to be tested for CTE routinely, or even better that anyone who is autopsied be studied for CTE, which could allow comparing, for example, the incidence of CTE in the football playing population with non players, and compare for example people who played in high school, people who played in college and people who played in the pros, and look at the percent with CTE.
Ultimately the real indication will be if they can come up with a test for CTE that can be done while people are alive, a brain scan that doesn’t require getting samples of brain tissue that can only be done after death. This would allow us to see what percent of active players in the NFL have the indications of CTE, retired players, and even do studies of college and high school players.
I think that the focus on changing the rules has helped, for example the jerk coaches who not too long ago were teaching kids to put their helmet down when running or or tackling, a couple of years ago I was watching a pee wee football game and saw kids putting their heads down and tackling and the coaches were applauding the ‘big hit’. Other fundamental changes might be putting weight limits in football, while I have no way of knowing (given how sparse CTE data still is), I suspect that incidences of CTE were lower decades ago, in the late 1960’s defensive linemen and O linemen weighed around 250 pounds or so , and they tended to be slow, today linemen are easily 300 pounds and over, and they are fast as well, basic physics says the amount of force being generated is much greater than back then (these days, 250 pounds is a typical weight of a linebacker).
As someone who has played the game, and also enjoy watching it, I am torn, but I don’t think the answer is to shrug it off or try and ‘prove’ as some posters on here or the many out there say, that since we don’t know how many people have CTE, what percent get it, we should assume it is something that may tragically affect a small number of players and not worry about it until we have more evidence that it is widespread, that is the wrong approach. I personally think we should limit kids before high school to flag football and for example, modify how kids are allowed to block and such, and also modify how high school players and beyond practice and the like. I think it is also appropriate of course to research if we can make the game safer (and not just use concussion numbers), maybe limiting things like the weight of players (personally, from what I have read by people like Damien Woody and others who have retired who were the “big men”, being that big takes a huge toll on their bodies as a whole and may not be so healthy, they don’t get to that size naturally, not saying steroids,but rather they have to do all kinds of crazy weight training and eating to get that big and fast). I think my priority (not that anyone would listen to me) would be in finding a test for living people, and also in how do we treat the victims of this.
And yes, other sports have seen CTE, not surprisingly, Rugby Players have been diagnosed with it post mortem, and I am sure that some players in other sports, or even for example some fighter pilots, race car drivers and the like might have it, but I would bet that because of the nature of football, with how many big hits they absorb all the time, they will have by far the most.
I don’t think the game is going anywhere, it is too big a business, both at the pro level and at the college level. My big fear is the industry and its supporters don’t turn this into another political football and try things like, for example, banning studying college football players or gathering data on CTE (if they can do it when they are alive) on players in their states as a way to try and protect the game, among other things, that will almost guarantee that if the CTE data is really really bad, the game will die, I am hoping with facts that the game can survive and the players know the risks, and also that there is a way to help treat them if it does happen. Unfortunately, I already have heard a lot of fans saying things like “of course football is violent, it is what the sport is, and if someone plays it, well, they take the risks of playing it” which is not only pathetic but also tells just how cold and selfish the person saying it is. As others have pointed out, sports often for some people is a way to a better life, division one football programs have 85 kids on football scholarships and a lot of them will never play ball, may not have decided to, but end up with enough education to do well, and they may be willing to take any risks to have that, but I think it is also our duty to make sure they know the exact risks, we do everything we can to protect them and treat them.
