I don't see much value in the straw man argument regarding head trauma caused by falling off a bike, etc.
What we're talking about is a virtual guarantee that if you participate in football, you'll end up with a degenerative neurological disorder due to repeated trauma. The jury isn't really out on this one, regardless of how "narrow" you feel the scope of this particular study is.
The CTE study has to be focused on dead athletes unfortunately, as it's currently the only way to diagnose it. 99/100 or so is fairly definitive I'd say.
