Now, Dr McKee admit that there is a definitive bias in her sample group. After all, most of the brains she looked at were donated by the families of ex-players who were already showing signs of CTE. But that doesn’t invalidate the findings. In fact, with more than 50% testing positive, the link to playing football is clear. Of the group, there were 44 linemen affected. Running backs were next, with 20 , and defensive backs offered 17 cases. Quarterbacks, wide receivers, and tight ends had some of the fewest, with seven, five, and two instances respectively.
