When I was a kid, I used to love the Rock'em Sock'em series from Don Cherry. The big crazy hits, the fights....Now, I cringe. We know so much more about head injuries now. Hockey is brutal (not as bad as footballl....but still), and fighting is just insane. I am legit scared someone is going to die on the ice from a head shot or fight. These dudes are huge now. They all workout and are strong as fuck. Back in the 80s, hardly anybody worked out in the offseason...
As for Simon, I'm sure his brain will show evidence of CTE. It would be shocking if it didn't. Just think of all the fighters who have died young. Wade Belak, Derek Borougad and many more....
