I do follow my own advice. My kid does not head clearance balls.1. It is the best study that has been presented here. If you got a better one, then it is incumbent upon you to show us. As I said, it should not be the last word. More research is definitely appropriate.
2. As to your second point ("if you desire to tell yourself that headers are safe, it satisfies that particular need..."), what your are really doing is accusing me of deductive reasoning, meaning that I have formed a conclusion and no contrary evidence will be admitted. As my posts show, I do not foreclose the possibility that headers might cause CTE, but the best evidence presented so far does not support that position.
3. You, however, have presented no evidence whatsoever except that one soccer player had CTE. From that shaky premise, you concluded that people should run away from coaches who teach heading. Then you went on to suggest that heading a soccer ball put soccer players in the same category as NFL players. Now, even when presented with evidence that soccer headers do not cause CTE, you accuse me of having my mind already made up.
4. I say that you are the one who has formed an opinion which "satisfies your particular need." In 10 or 15 years we will know if your opinion is correct. For right now, though, it is unsubstantiated.
5. Until then, follow your own advice. Put your child with a coach who doesn't teach headers. Or take your child out of soccer.
There is plenty of evidence that concussions and sub-concussive impacts are a problem in soccer. The nature of that relationship is the sort of thing they write survey articles about:
To present one of those 100 or so studies and say “here’s the last word“ or “this is the best study” is kind of silly.
