First, this is obviously about Kevin Turner. I hope his family is well supported by those that know them personally as they deal with his death. If the things described as a result of this disease (never having personally encountered it) are any where near accurate, I also hope that his passing provides a measure of relief to those who cared for him.
Less importantly, *IF* this truly was (as he was trying to prove) a result of his on field injuries related to repetitive impact or concussion injuries it leaves me feeling in an uncomfortable way. I understand that players are going to make choices about their bodies and injuries versus their future and that of their family's future. But I've always rationalized that having a wonky hip or a bad knee or mangled fingers isn't much different from the guy who builds stone walls for 40 years - and the pay is certainly better. But brain injuries/damage is a whole other animal. Honestly I don't feel so good today about supporting the environment that leads to this kind of impact, especially given that medical data was denied, withheld, misrepresented, etc. to the players.
RIP Mr. Turner.
