1. Aaron Hernandez
There was a time when Hernandez and Rob Gronkowski were the top tight end duo in the NFL. Sadly, Hernandez has one of the darkest criminal convictions on this list after he murdered Odin Lloyd. Furthermore, investigations link him to several other homicides. In the end, Hernandez, a closet bisexual and abuse sufferer, killed himself in prison.
“There’s actually a lot that’s come out about his childhood and some repressed issues he had. I’m not excusing what he did but he had a really f***ed up life. And there’s no “may have had CTE” about it, he had one of the more advanced cases they had ever seen,” @drew_bare observed. Of course, this doesn’t take away the tragedy that occured nor the suffering of the victims. But it shows the need for an investigation into CTE in contact sports.
