Henry had the brain injury, I'm sure of that but I don't buy the bad behaviors being directly linked to it. Sometimes a guy is just an A-hole.
If this was the cause of his behavior then he couldn't have been "turning his life around" as so many people say he was, he'd be powerless to do so. I think this can cause neurological problems, like Mike Websters*, but using it to excuse someone for being an A-hole is something I'm very skeptical about. There are a lot of A-holes who've never had head trauma. More importantly though, IMO, is that the vast majority of football players walk away from the game without violent tendencies and are able to cope with life in general effectively. Steve Tasker, Bruce Smith, Thurman Thomas, Darryl Talley, etc. etc. Offensive and defensive linemen bang heads on every play and, I'm only going by my perception, it doesn't seem there is a radical difference in their positions in regards to the number of violence related cases among football players. There are many boxers who have led productive lives after boxing too. George Forman went from being an A-hole to being a much better person after his career.
I can already hear the defense attorney's licking their chops. How long will it be before somebody says OJ's behavior was the result of constant head banging. It wasn't OJ that beat his wife and killed Ron and Nicole, it was his battered brain. MV only found joy in torturing and killing dogs because he played football and suffered head injuries. Rae Carruth planned his girlfriends murder and helped execute it due to head injuries. Travis Henry is a dope dealer due to head injuries.
I'm inclined to believe that the A-hole tendencies of some players are the result of being coddled for the majority of their lives because they are star athletes.
I'd be very interested in finding out how many of the guys that were found to have had this had uncontrollable problems in their lives.
*from the article;
CTE carries specific neurobehavioral symptoms, Bailes said – typically, failure at personal and business relationships, use of drugs and alcohol, depression and suicide.
These things should be showing up in the majority of players if the cause and effect is to be believed. JMO
