  I prefer this comparison to the GP's since it controls for the level of medical technology. There may have been a spate of deaths in the early 20th century, but they may not have happened today. Not to mention that a single year could be an extreme outlier.

  Aside from a similar ball shape, Australian rules football is nothing like American football.

  The article isn't about concussions. It's about hits that do not cause one to show visible mental effects, but are in fact a very mild form of concussion (TBI). And it's about players thousands upon thousands of those hits throughout their life.
