This is disturbing, but does help bring the subject of depression and mental illness into the limelight. It also raises the issue of concussions in football, though there is no factual evidence in this particular case.
I doubt concussions have any issue to do with this. The player was too young. It takes time and repetition for concussions to have an impact on the brain. The most likely culprit is the combination of depression and easy access to deadly weapons.
Remember, every 17 minutes in the US a person’s life comes to an end thanks to those that support the NRA and those that support unlimited access to whatever firearms they can get their hands on.
They are going to do an autopsy on his brain, we’ll have more answers from that.
I don’t know if he was too young – one would figure that he presumably started as a young tot in Pop Warner. Middle school, high school, four years of college (he was a senior), as a lineman especially, that’s a lot of blows to the head. A lot of time and repetition.
